Product Technical Details

Product Overview

DL-Leucine, chemically known as 2-Amino-4-methylpentanoic acid, represents a critical racemic amino acid utilized extensively across the nutraceutical and pharmaceutical industries. As an essential branched-chain amino acid, this compound serves as a fundamental building block for protein synthesis and metabolic regulation. Our manufacturing process ensures that every batch meets rigorous international standards, providing a reliable supply chain partner for formulators seeking consistency and quality.

Unlike its L-isomer counterpart, DL-Leucine offers unique stability profiles and cost-effectiveness for specific industrial applications where optical purity is not the primary constraint. This makes it an ideal choice for bulk supplementation, animal nutrition, and specialized chemical synthesis routes. We maintain strict control over production parameters to guarantee low impurity levels and high assay values.

Industrial Applications

The versatility of DL-Leucine allows for integration into various downstream products. In the nutraceutical sector, it is frequently employed as a dietary supplement ingredient to support muscle recovery and metabolic health. Pharmaceutical manufacturers utilize this compound as an intermediate in the synthesis of more complex therapeutic agents. Additionally, it serves as a valuable component in cosmetic formulations where amino acid balance is required for skin conditioning.

Our clients benefit from a material that offers excellent flow properties and solubility characteristics, facilitating easier processing during tablet compression or liquid formulation. Whether used as a standalone supplement or as part of a complex amino acid blend, DL-Leucine provides the necessary structural integrity and biological activity required for high-performance end products.

Quality Assurance and Storage

We adhere to Good Manufacturing Practices (GMP) to ensure product safety and consistency. All materials are stored in controlled environments to prevent moisture absorption and degradation. Packaging is designed to maintain integrity during global transit, ensuring that the product arrives at your facility in optimal condition. Certificates of Analysis (COA) are provided with every shipment, detailing batch-specific test results for full transparency.

For long-term storage, we recommend keeping the container tightly closed in a cool, dry place away from direct sunlight. Proper handling procedures should be followed to maintain the chemical stability of the amino acid powder. Our technical support team is available to assist with formulation guidance and regulatory documentation to streamline your production processes.
