Quality Control

Our 4-[7-(Acetyloxy)-3,4-Dihydro-2H-1-Benzopyran-3-Yl]-1,3-Benzenediol Diacetate is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing specific results for purity, related substances, and residual solvents are provided and available upon request, supporting compliance in regulated environments.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
