Quality Control

Our N~4~-Phenylasparagine(Saltdata: Free) is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, chiral analysis, and spectroscopic identification, to ensure it meets the high standards required for research and development applications. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming identity, purity, and other critical parameters.

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 absorption, which may affect stability and handling properties.
