Quality Control

Our 8,9-Dihydro-5,8-Dihydroxy-8-Hydroxymethyl-2-Methyl-4H-Pyrano[3,2-H][1]Benzoxepin-4-One is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, IR and NMR for structural confirmation, and tests for residual solvents and moisture. Certificates of Analysis (COA) documenting all specifications are provided to ensure traceability and compliance with your research or manufacturing requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area 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 the use of desiccants.
