Description

L-Ornithine 2-Oxoglutarate is a stable, pharmaceutically relevant salt formed from the amino acid L-Ornithine and 2-Oxoglutaric acid. This compound is valued for its role in supporting metabolic pathways, particularly in the urea cycle and amino acid synthesis. It is primarily utilized by manufacturers in the pharmaceutical and nutraceutical industries for the formulation of clinical nutrition products, dietary supplements, and metabolic support agents.

Application

• Pharmaceutical Intermediates: Serves as a key active pharmaceutical ingredient (API) or precursor in metabolic and hepatoprotective medications.
• Clinical Nutrition: Incorporated into parenteral and enteral nutrition solutions for patients requiring metabolic support, such as in post-surgical recovery or critical care.
• Dietary Supplements: Used as a core component in sports nutrition and wellness supplements aimed at promoting muscle recovery, ammonia detoxification, and liver health.
• Biochemical Research: Employed as a standard or reagent in metabolic studies, enzymatic assays, and research on the urea cycle and amino acid metabolism.
• Veterinary Pharmaceuticals: Applied in formulations for animal health, supporting metabolic function in livestock and companion animals.

Quality Control

Our L-Ornithine 2-Oxoglutarate is produced 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) detailing identity, purity, and impurity profiles are provided with 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); the container must be kept tightly sealed in a dry environment to prevent absorption of moisture and caking.
