Description

L-Arginine 2-Oxopentanedioate is a high-purity, pharmaceutically relevant salt form of the essential amino acid L-Arginine. This compound is valued for its enhanced stability and bioavailability compared to the free base, making it a critical intermediate in advanced therapeutic and nutraceutical formulations. It is primarily sought by manufacturers in the pharmaceutical, dietary supplement, and advanced biomedical research sectors for developing products that support cardiovascular health, immune function, and metabolic processes.

Application

• Pharmaceutical Intermediates: A key building block in the synthesis of peptide-based drugs and active pharmaceutical ingredients (APIs) targeting nitric oxide pathways.
• Dietary Supplements & Nutraceuticals: Used in premium-grade formulations for sports nutrition, cardiovascular support, and immune system boosters due to its role as an arginine source.
• Biochemical Research: Serves as a standardized reagent in cell culture studies, enzymatic assays, and metabolic research focusing on the urea cycle and nitric oxide synthesis.
• Cosmeceuticals: Incorporated into advanced skincare products for its purported role in promoting collagen synthesis and skin barrier function.
• Veterinary Pharmaceuticals: Utilized in specialized feed additives and therapeutic preparations for livestock and companion animals.

Quality Control

Our L-Arginine 2-Oxopentanedioate is manufactured under strict quality management systems. Each batch is tested to meet high-purity standards suitable for pharmaceutical and nutraceutical applications. We provide comprehensive Certificates of Analysis (COA) that detail specifications for identity, purity, and impurities. Our quality commitment ensures compliance with relevant guidelines for cGMP and ISO 9001 standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed in a dry environment to prevent absorption of moisture from the air, which can affect stability and handling properties.
