Description

L-Lysine Dihydrochloride is the dihydrochloride salt form of the essential amino acid L-Lysine, a critical building block for protein synthesis. This high-purity form offers superior stability and solubility, making it an indispensable ingredient for precise nutritional and biochemical applications. It is primarily utilized by manufacturers in the pharmaceutical, nutraceutical, and food & beverage industries seeking a reliable source of bioavailable lysine.

Application

• Pharmaceutical Formulations: Used as a key raw material in parenteral nutrition (IV solutions), amino acid infusions, and solid dosage forms to correct lysine deficiency.
• Dietary Supplements & Nutraceuticals: Incorporated into protein powders, sports nutrition products, and general health supplements to support muscle protein synthesis and overall wellness.
• Food & Beverage Fortification: Serves as a nutritional fortifier in cereals, baked goods, and beverages to enhance the protein quality and nutritional profile of finished products.
• Cell Culture Media: Acts as an essential component in defined media for the cultivation of mammalian cells in biopharmaceutical production and research.
• Biochemical Research: Employed as a standard or reagent in enzymatic studies, metabolic research, and as a substrate in various biochemical assays.
• Animal Feed Additive: Used in premium aquafeed and livestock feed to ensure optimal growth and feed efficiency by meeting essential amino acid requirements.

Quality Control

Our L-Lysine Dihydrochloride is manufactured under strict quality management systems. It is typically tested to meet or exceed relevant industry standards such as USP, EP, and FCC for applicable grades. Every batch is supported by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles to ensure compliance with your specific requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture.
