Description

L-Ornithine Dihydrochloride is a high-purity, pharmaceutically relevant salt of the non-proteinogenic amino acid L-Ornithine. This compound is essential as a key intermediate in the urea cycle and serves as a critical building block for various biochemical syntheses. It is primarily utilized in the pharmaceutical, nutraceutical, and research sectors for the development of metabolic supplements, parenteral nutrition solutions, and as a precursor in peptide synthesis.

Application

• Pharmaceutical Intermediates: A crucial raw material in the synthesis of hepatoprotective drugs, arginine, and other amino acid-based therapeutics.
• Nutraceutical & Dietary Supplements: Used in formulations aimed at supporting liver health, ammonia detoxification, and athletic performance due to its role in the urea cycle.
• Research & Development: Serves as a standard and reagent in biochemical research, metabolic studies, and cell culture media preparation.
• Parenteral Nutrition: Incorporated into intravenous amino acid solutions for clinical nutrition, especially in patients with hepatic conditions.
• Peptide Synthesis: Acts as a protected amino acid building block in solid-phase and solution-phase peptide chemistry.
• Cosmetic Ingredients: Utilized in advanced skincare formulations for its purported skin rejuvenation and moisturizing properties.
