Quality Control

Our 2-[3,4-Bis(Acetoxy)Phenyl]-3,4-Dihydro-2H-1-Benzopyran-3,5,7-Triyl Triacetate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (typically ≥95% to ≥98%), to ensure it meets the stringent requirements for research and development applications. Certificates of Analysis (COA) detailing all test results are provided with every shipment to guarantee traceability and compliance with your specifications.

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.
