Quality Control

Our S-Phenyl-L-Cysteine-n-(3-Aminophenyl)Amide is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chiral purity verification by HPLC, to ensure it meets the high standards required for pharmaceutical research. A detailed Certificate of Analysis (COA) documenting identity, purity, and impurity profiles is 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 (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider desiccants or an inert atmosphere.
