Quality Control

Our Cystathionamine is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, chiral analysis for stereochemical integrity, and residual solvent screening. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to ensure traceability and compliance with your research or cGMP guidelines, where applicable.

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 must be kept tightly sealed in a dry environment to prevent moisture absorption. For long-term storage, consider desiccants or inert atmosphere.
