Description

L-Lysine Hydrochloride is the hydrochloride salt form of the essential amino acid L-Lysine, a critical building block for protein synthesis. This high-purity ingredient is vital for formulating balanced nutritional and pharmaceutical products where precise amino acid profiles are required. It serves as a fundamental raw material for manufacturers in the animal feed, food fortification, pharmaceutical, and nutraceutical industries worldwide.

Application

• Animal Feed Additive: A primary application, used to supplement lysine-deficient diets (e.g., corn-based) for poultry, swine, and aquaculture to optimize growth, feed efficiency, and muscle development.
• Food & Beverage Fortification: Incorporated into cereals, flour, nutritional bars, and dietary supplements to enhance protein quality and meet nutritional labeling claims.
• Pharmaceutical Intermediates: Serves as a key chiral starting material or active ingredient in parenteral nutrition solutions, infusion preparations, and therapeutic amino acid formulations.
• Cell Culture Media: An essential component of defined media for the cultivation of mammalian cells in biopharmaceutical production and research.
• Microbiological Media: Used in nutrient broths and agars to support the growth of specific microorganisms in industrial fermentation and diagnostic applications.
• Cosmetic & Personal Care: Employed in hair care and skin care products for its purported moisturizing and conditioning properties.

Quality Control

Our L-Lysine Hydrochloride is manufactured under strict quality management systems. We offer grades compliant with relevant industry standards, including Feed Grade, Food Grade (FCC), and Pharmaceutical Grade (USP). Every batch undergoes rigorous analytical testing to ensure identity, purity, and safety. Comprehensive Certificates of Analysis (COA) documenting all critical parameters are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed after each use to prevent absorption of atmospheric moisture, which can lead to caking and degradation.
