Quality Control

Our 3,4-Dihydro-2-(4-Hydroxyphenyl)-2H-1-Benzopyran-3,4,5-Triol is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing including HPLC for purity, identity confirmation by IR and NMR, and residual solvent analysis to ensure it meets stringent specifications for research and industrial use. Certificates of Analysis (COA) documenting all test results are provided with every shipment.

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 sensitivity to oxidation, long-term storage under an inert atmosphere (e.g., nitrogen or argon) is recommended for optimal stability. Keep away from strong oxidizing agents.
