Quality Control

Our 3,4-Dihydro-3-Methyl-2-Phenyl-2H-1-Benzopyran-3,4-Diol is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and chiral analysis, to ensure it meets the high standards required for research and development applications. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available upon request to support your quality assurance and regulatory needs.

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 opening to prevent degradation from atmospheric moisture.
