Quality Control

Our Pentanoic Acid, 4,5-Diamino-5-Oxo-, Phenylmethyl Ester, Monohydrochloride, (R)- is manufactured under strict quality systems. Each batch undergoes rigorous analytical testing, including chiral purity verification by HPLC, to ensure compliance with stringent specifications for pharmaceutical R&D use. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container should be kept in a desiccated environment to prevent moisture uptake. For long-term storage, consider inert gas purging.
