Quality Control

Our (S)-2-Amino-3-Methyl-n-Phenylbutanamide is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chiral purity verification by HPLC, to ensure it meets the exacting standards required for research and development applications. Certificates of Analysis (COA) detailing identity, purity, and chiral excess 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 absorption, which may affect stability and handling properties.
