Quality Control

Our [1]Benzopyrano[5,4,3-Cde][1]Benzopyran-5,10-Dione, 3-[(6-Deoxy-α-L-Mannopyranosyl)Oxy]-2,7-Dihydroxy-8-Methoxy- is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (NMR, MS), to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) detailing all specifications are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture. For long-term storage, consider desiccants or an inert atmosphere.
