Quality Control

Our Cyclo(L-Ala-D-Thr-L-Cys(1)-L-Pro-L-Ala-L-Trp2(1)-4-Hydroxy-L-Leu-) is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and MS for identity confirmation, to ensure it meets the high standards required for research and development applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and related substances 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 desiccated conditions.
