Quality Control

Our Cyclo(-Phe-Ser) is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and chiral integrity, to ensure it meets the high standards required for research and development. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming identity, purity, and specification compliance.

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 product degradation.
