Quality Control

Our 4-Amino-2-(S-Cysteinyl)Butyric Acid is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and pharmaceutical applications. Certificates of Analysis (COA) detailing all specifications are available upon request.

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 and easily oxidized nature, it is recommended to store the product under an inert atmosphere (e.g., nitrogen or argon) and handle it in a moisture-controlled environment to ensure long-term stability.
