Description

L-Lysine, Compound With 5-Oxo-L-Proline (1:1) is a high-purity, non-hygroscopic salt form of the essential amino acid L-Lysine, offering enhanced stability and handling properties. This compound is critical for applications requiring a bioavailable and consistent source of lysine, a fundamental building block for protein synthesis. It is primarily utilized in the pharmaceutical industry for parenteral nutrition formulations and as a key intermediate in advanced peptide synthesis.

Application

• Pharmaceutical Active Pharmaceutical Ingredient (API): Used in intravenous (IV) amino acid solutions for total parenteral nutrition (TPN) to correct nitrogen balance.
• Dietary Supplement & Nutraceutical Precursor: Serves as a stable raw material for the manufacture of lysine-based dietary supplements.
• Biochemical Research & Cell Culture: Employed in media formulation for mammalian cell culture and as a standard in analytical research.
• Peptide Synthesis Intermediate: Acts as a protected or modified lysine derivative in the solid-phase synthesis of therapeutic peptides.
• Veterinary Medicine: Incorporated into feed additives and injectable solutions for livestock and companion animals.
