Description

L-Ornithine (4-Methyl-2-Oxopentanoate) is a high-purity salt form of the amino acid L-Ornithine, combining it with 4-Methyl-2-oxopentanoic acid. This compound is valued for its enhanced stability and bioavailability compared to the free amino acid, making it a critical intermediate in advanced biochemical synthesis and nutritional formulations. It is primarily utilized by manufacturers in the pharmaceutical, nutraceutical, and research sectors for developing metabolic support products, parenteral nutrition, and specialized cell culture media.

Application

• Pharmaceutical Intermediates: Key building block for the synthesis of specialized drugs targeting liver health, ammonia metabolism, and wound healing.
• Sports Nutrition & Dietary Supplements: Formulated into powders, capsules, and ready-to-drink products aimed at enhancing athletic performance, recovery, and growth hormone support.
• Clinical Nutrition: Essential component in parenteral (IV) and enteral nutrition solutions for patients with specific metabolic needs or under catabolic stress.
• Biochemical Research: Used as a precursor in enzymatic studies, metabolic pathway analysis, and the production of other bioactive compounds.
• Cell Culture Media: Incorporated into specialized media formulations to support the growth of demanding cell lines in biopharmaceutical production.
• Cosmeceuticals: Found in advanced skincare formulations for its purported role in collagen synthesis and skin repair mechanisms.

Quality Control

Our L-Ornithine (4-Methyl-2-Oxopentanoate) is manufactured under strict quality management systems. Each batch is tested to ensure it meets high-purity standards suitable for pharmaceutical and nutraceutical applications. Certificates of Analysis (COA) documenting identity, purity, and specific impurities are available for every shipment. We can support compliance with relevant pharmacopeial standards (e.g., USP, EP) upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept in a dry environment to prevent caking and degradation. Keep the container tightly sealed after each use.
