Quality Control

Our (6As)-5,6Aα,7,12Aβ-Tetrahydro-2,3,10-Trimethoxy[2]Benzopyrano[4,3-B][1]Benzopyran-7α-Ol is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and chiral purity assessment, to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) with detailed chromatographic data are available upon request to support your regulatory and quality assurance needs.

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 using desiccants.
