Description

DL-Lysine Dihydrochloride is a high-purity, crystalline salt form of the essential amino acid lysine, widely recognized for its stability and solubility. This compound is critical for applications requiring a readily available source of lysine, particularly where the L-form's biological activity is not the primary requirement. It serves as a fundamental building block and biochemical reagent for the pharmaceutical, nutraceutical, and research sectors, as well as in specialized industrial processes.

Application

• Pharmaceutical Intermediates: Used in the synthesis of active pharmaceutical ingredients (APIs) and as a component in parenteral nutrition solutions.
• Biochemical Research & Cell Culture: Serves as a key nutrient in microbiological media and cell culture formulations for laboratory and bioprocessing applications.
• Animal Nutrition & Feed Additives: Incorporated into feed premixes to supplement amino acid profiles, supporting animal growth and health.
• Food & Beverage Fortification: Acts as a nutritional supplement in food products designed for specific dietary management.
• Cosmetic & Personal Care: Utilized in hair and skin care formulations for its conditioning and moisturizing properties.
• Chemical Synthesis: Employed as a chiral starting material or reagent in organic synthesis and peptide chemistry.

Quality Control

Our DL-Lysine Dihydrochloride is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets high-purity standards suitable for pharmaceutical and nutritional applications. Certificates of Analysis (COA) detailing specific results for identity, purity, and impurities are provided with every shipment. We can supply material compliant with various pharmacopeial standards (e.g., USP, EP) upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept in a dry environment to prevent caking and degradation.
