Quality Control

Our L-Arginine Mono(4-Methyl-2-Oxovalerate) is manufactured under strict quality management systems. Each batch is tested to ensure it meets stringent specifications for identity, purity, and potency, suitable for pharmaceutical and nutraceutical applications. Certificates of Analysis (COA) documenting comprehensive testing via HPLC, IR, and other pharmacopeial methods are available upon request to support your regulatory and quality assurance needs.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect stability and handling properties.
