Description

L-Lysine is an essential amino acid crucial for protein synthesis and various metabolic functions in humans and animals. Its high commercial value stems from its role as a critical nutritional supplement and a versatile building block in pharmaceutical synthesis. This product is indispensable for manufacturers in the animal feed, food fortification, and pharmaceutical industries seeking a reliable, high-purity source of this vital nutrient. We supply L-Lysine CAS NO 6899-06-5 to meet the stringent quality demands of global B2B markets.

Application

• Animal Nutrition: Primary use as a feed additive for poultry, swine, and aquaculture to optimize growth performance and improve feed efficiency by balancing amino acid profiles in cereal-based diets.
• Human Nutrition & Food Fortification: Key ingredient in dietary supplements, infant formula, and fortified foods (e.g., cereals, wheat flour) to enhance protein quality and address lysine deficiencies.
• Pharmaceutical Intermediates: Serves as a chiral building block in the synthesis of various active pharmaceutical ingredients (APIs) and intravenous nutritional solutions.
• Cosmetic & Personal Care: Used in hair care and skin care formulations for its moisturizing properties and role in collagen production.
• Cell Culture Media: An essential component of media used in biotechnology and pharmaceutical research for mammalian cell cultivation.

Quality Control

Our L-Lysine is manufactured under strict quality management systems. Each batch is tested to ensure it meets relevant specifications for Feed Grade (FAMI-QS), Food Grade (FCC), or Pharmaceutical Grade (USP/EP) as required. Comprehensive testing includes assay, optical rotation, residue on ignition, and specific tests for heavy metals and related substances. A Certificate of Analysis (COA) is provided with every shipment to guarantee traceability and compliance.

Storage

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