Product Name L-Citrulline DL Malate This compound represents a non-proteinogenic amino acid (L-Citrulline) reacted with DL-malic acid. The L-form is targeted during production due to its bioactivity and relevance in nutritional, food, and sports supplement markets. Malate may be included in various stoichiometries; the 2:1 salt is commonly demanded in industrial contracts, but other ratios can be processed depending on the customer's solubility or taste-masking needs. Commercial volumes follow the nomenclature specified by the client.
IUPAC Name (S)-2-Amino-5-(carbamoylamino)pentanoic acid compound with (±)2-hydroxybutanedioic acid Strict adherence to IUPAC naming is followed on COAs as it helps clients track regulatory status and satisfies customs or compliance documentation for multi-national shipments. Different suppliers may reference synonyms, but consistent application of the full IUPAC convention is required by larger buyers on procurement documents.
Chemical Formula C6H13N3O3 • C4H6O5 (most common form: 2:1 ratio) The molecular formula in production documents always references the dominant commercial form, which is typically the 2:1 salt (2 parts L-Citrulline, 1 part DL-malic acid). Some custom-formulated supplements use other ratios; the exact formula must be matched to customer specification and printed on containers for ingredient traceability. Analytical release may adjust to non-stoichiometric ratios if downstream blending is involved.
Synonyms & Trade Names Citrulline Malate, L-Citrulline Malate, DL-Malic Acid Salt of L-Citrulline, L-Citrulline-2-malate Alternative labeling is frequent in international trade. The trade name is chosen according to regional documentation standards and contract terminology. Bulk shipments and private- or white-labeled blends adopt commercial synonyms most recognizable to end users. Each synonym may be standardized to reflect the chosen salt ratio, which always needs to be confirmed with final recipients to prevent logistics errors or customs delays.
HS Code & Customs Classification 2922.49 This code covers amino acid derivatives and their salts including citrulline malate. Customs processes often review specificity of formulation, so shipments need supporting composition analysis and compliance evidence reflecting amino acid origin, purity grade, and whether the malic acid moiety is of natural or synthetic origin.

L-Citrulline DL Malate: Technical Properties, Manufacturing Process & Safety Guidelines

Physical & Chemical Properties

Physical State & Appearance

Commercial L-Citrulline DL Malate generally appears as a white to off-white crystalline powder. Odor remains minimal and characteristic of the amino acid category. The melting point range typically fluctuates depending on the ratio of citrulline to malate and moisture level present during crystallization and storage. Observing unexplained agglomeration, discoloration, or off-odors can indicate hydrolytic or microbial degradation—operators note these changes during lot release and in-process checks.

Melting Point, Boiling Point, Flash Point, Density

Exact thermal data can shift based on grade type and citrulline-to-malate ratio. As a non-volatile, crystalline solid built for water miscibility, boiling and flash points remain irrelevant in standard process and end-use, and density measurements—used primarily for bulk handling and tablet compression—will differ by particle size, granulation, and moisture content.

Chemical Stability & Reactivity

L-Citrulline DL Malate shows robust shelf stability at ambient laboratory conditions, avoiding reactivity with stainless steel, common plastics, or glassware. Long-term exposure to high humidity or elevated heat may initiate caking, hydrolysis, or surface discoloration—issues traceable back to deviations in storage protocol, product grade, or batch moisture profile.

Solubility & Solution Preparation

Full dissolution in water occurs under ambient or mildly elevated temperature; clarity depends on both input purity and water quality. Operators preparing concentrated stock must monitor pH and ionic strength, since solution haze or precipitate formation signals deviation from spec or contamination by impurity ions. Food and pharma applications often require microbiological control during dissolution, addressed through validated solution filtration.

Technical Specifications & Quality Parameters

Specification Table by Grade

Standard technical and nutraceutical grades differ in purity targets, residual solvent levels, and allowable impurity profiles. The specification sheet for each batch lists appearance, identification by IR/HPLC, assay (citrulline content, malic acid content), moisture (Karl Fischer), pH (in solution), residue on ignition, and heavy metals. For sports, food, or pharma grades, additional parameters such as microbial profile and allergen status follow customer contract or market regulation.

Impurity Profile & Limits

Common impurities arise from incomplete reaction or side-chain hydrolysis in raw material streams or during thermal processing. The impurity spectrum depends on the reaction route (fermentation-based versus chemical synthesis). Each batch undergoes specific chromatographic analysis for structurally similar amino acids, unreacted malic acid, and process-related solvents or catalysts. Internal release criteria tighten these limits for higher grades.

Test Methods & Standards

Quality control uses compendial and in-house validated methods, typically HPLC, GC, IR-spectroscopy, and titration as appropriate for the constituent. The applicability and strictness of test standards adapt to the market destination and customer specifications, with batch release guided by both method performance and reproducibility of QC outcomes.

Preparation Methods & Manufacturing Process

Raw Materials & Sourcing

Raw citrulline and DL-malic acid are procured based on supplier audit outcomes, consistency in chemical analysis, and contaminant testing history. Supplier changes or region-driven raw material variability influence impurity load and require requalification.

Synthesis Route & Reaction Mechanism

Production uses a direct neutralization and crystallization reaction, blending pure L-citrulline with DL-malic acid in defined molar ratios under water or ethanol solvent conditions. The resulting salt crystallizes upon controlled solvent removal. Key selection factors for route include purity, cost efficiency, energy profile, and downstream processing adaptability.

Process Control & Purification

Key control points include real-time monitoring of reaction pH, temperature, and solution clarity, determining endpoint via titration or spectroscopic checks. Isolated crystalline product undergoes repeated washing and, if specified, filtration or recrystallization for impurity reduction. Strict batch traceability tracks critical process variables across each production lot.

Quality Control & Batch Release

Quality assurance inspects each lot against both internal standards and contractual customer requirements, prioritizing consistency in assay, moisture, microbiological data, and impurity panel. Deviations trigger root cause and corrective process adjustment before product release.

Chemical Reactions & Modification Potential

Typical Reactions

At process scale, L-Citrulline DL Malate does not undergo further intended modification. Potential reactions—hydrolysis, Maillard-type browning, or salt dissociation—arise under adverse handling, thermal stress, or contaminated environments. Laboratory-scale derivatization remains application-specific, often linked to custom API or excipient requests.

Reaction Conditions

Manufacturing avoids the use of aggressive catalysts or hazardous solvents, preferring water or ethanol as the reaction medium. Process temperature and solvent ratios influence yield and impurity carryover, monitored via in-process analytics.

Derivatives & Downstream Products

Formulators may use the raw salt in sports nutrition blends, pharmaceutical intermediates, or as a functional food ingredient; further chemical modification is uncommon outside of specialty synthesis environments. Downstream performance depends on consistency in primary salt composition and low impurity background.

Storage & Shelf Life

Storage Conditions

L-Citrulline DL Malate longevity depends on low humidity, moderate temperatures, and avoidance of direct sunlight or intense artificial light. Excess moisture or environmental CO2 increases risk of hydrolysis or acidification, monitored through periodic stability testing. Facility protocols specify storage in clean, dedicated spaces to avoid cross-contamination.

Container Compatibility

Contact with food-grade polyethylene, HDPE, and glass containers meets regulatory standards for both technical and food grades. Direct exposure to reactive metals—non-stainless steel or copper—should be avoided to eliminate risk of trace metal uptake.

Shelf Life & Degradation Signs

Real-life shelf life depends on batch moisture and storage discipline; tablets and blended powders can exhibit caking, yellowing, or odor shift as early warning of degradation. The stability program defines shelf life expectations and trend data per market requirements.

Hazard & Precautionary Statements

Operators avoid dust inhalation and skin or eye contact by following routine PPE guidance and engineered ventilation controls. Handling large volumes encourages prompt spill containment, dry sweeping, and clean transfer practices to minimize exposure. Food or pharmaceutical manufacturing audits also require trace allergen and cross-contact documentation.

Toxicity Data

Existing toxicology studies—referenced in technical literature and regulatory filings—find negligible acute oral or dermal toxicity at exposure levels relevant to ingredient production. Chronic exposure evaluations and allergenicity assessments are grade- and market-dependent, driven by customer and regulator inquiry.

Exposure Limits & Handling

Regulatory exposure guidelines originate from workplace particulate limits. Real-time dust monitoring, engineering containment, and routine surface cleaning support compliance in facility operations. Final packaging operations require labeling that aligns with transit and handling standards relevant to declared hazard class.

Supply Capacity & Commercial Terms for L-Citrulline DL Malate

Production Capacity & Availability

Output levels of L-Citrulline DL Malate closely track available malic acid and citrulline intermediate stock. Plant-scale capacity varies by synthesis route and the degree of continuous vs. batch operation, and production scheduling aligns with forecasted demand in sports nutrition and supplement channels. Output is typically constrained more by fermentation time for L-arginine (precursor) and reactor occupancy than by raw material supply, provided commodity-grade DL-malic acid sources remain stable. For high-purity food and nutritional grades, capacity is also tied to the availability of food-compliant intermediates and purification lines set aside from industrial malate production.

Lead Time & MOQ

Typical quoted lead times range from four to eight weeks for standard grades, provided that core raw materials are not affected by logistic bottlenecks. Custom sizing, special packaging, or certifications (such as organic or major retailer requirements) may extend lead times. Production is batch-based for specialty grades, and the minimum order quantity can depend on batch size, downstream filling configurations, and customer inventory restocking policies rather than a single fixed value. For direct shipment, MOQ is governed by container or pallet economics.

Packaging Options

Bulk packaging uses multi-layer kraft bags with polyethylene liners or fiber drums with tamper-proof seals, protecting against moisture ingress and contamination. Food and pharma grade orders often add outer cartons or additional lining depending on regulatory or customer-specific hygiene protocols. Custom weights can be arranged, subject to filling and labeling line constraints.

Shipping & Payment Terms

Direct shipments follow Incoterms reflecting customer risk tolerance, with FOB, CIF, and DDP available based on the buyer's logistics chain control. Sea freight dominates for non-perishable grades, while air shipment answers urgent or smaller-scale orders. Payment terms usually depend on business history, regulatory background checks, and customer credit, with new contracts requiring advance or sight LC, and trusted partners working on net terms. Regulatory filing and pre-shipment inspection requirements in destination markets can impact readiness for shipment.

Pricing Structure & Influencing Factors

Raw Material Cost Composition

Raw material cost roots in synthetic DL-malic acid and fermentation-derived L-citrulline, both seeing price volatility due to feedstock market shifts. For malic acid, the decisive factor is upstream maleic anhydride, which tracks oil and n-butane prices. L-citrulline’s cost is linked to cane or corn sugar fermentations, with sugar pricing and energy costs forming the base. Utilities, water, and purification reagents round out the rest.

Fluctuation Causes

Raw material pricing rises on feedstock shortages, energy shocks, or logistical interruptions at ports of origin. High demand from sports and pharmaceutical segments can distort spot pricing, especially during athletic events or post-pandemic supplement surges. Scrutiny of supply chain sustainability (such as requests for non-GMO or vegan claims) further reshuffles sourcing costs and price points.

Graded Price Differences & Product Price Difference Explanation

Final price hinges on grade: food and pharmaceutical grades command higher premiums versus industrial or technical grades due to more intensive purification, stricter release tests, and compliance documentation. Higher purity grades undergo additional recrystallization, filtration, and microbe testing, which increases production costs and completed batch lead time. Specialty packaging, kosher/halal or allergen-free certifications incur documentation and inspection overhead. Bulk shipments for feed or technical grade see lower unit cost per metric ton, while small-lot food or pharma grades reflect higher per-kilo handling and compliance costs, especially when customers require batch tracing or third-party audits.

How to Select the Right Grade

Step 1: Define Application

Start by clarifying the end-use context. A sports powder mixture calls for organoleptics and flowability. A parenteral-grade pharmaceutical admixture requires strict control over trace contaminants and sterile handling. Clear application definition stations the right technical requests for the subsequent screening.

Step 2: Identify Regulatory Requirements

Compliance teams reference dietary supplement code, food additive status, or pharmacopeial monographs. If end-product distribution crosses regions, regulatory expectations shift and impact not only grade selection but also documentation and traceability requests.

Step 3: Evaluate Purity Needs

Pilot trials examine how much impurity residual can be tolerated in the application. Food and sports nutrition often prioritize microbiological specs and flavor. Parenteral or high-purity compounding grades tie into advanced purification and extended analytics. Both upstream raw material characterization and downstream traceable release are part of the evaluation loop.

Step 4: Consider Volume & Budget

Technical and procurement teams weigh batch size and multi-lot supply agreements. Higher purity or compendial grades impact manufacturing overhead. Output stability and shelf management drive decisions in favor of larger or smaller lot sizes depending on the operational forecast and ability to warehouse under controlled humidity conditions.

Step 5: Request Sample for Validation

Before approving any bulk order, QA and product development teams run application-specific validation trials. Real-use tests on blending, tableting, solubility, or stability under customer storage simulate downstream performance.
