Quality Control

Our 8-[(3,4-Dihydro-3,5,7-Trihydroxy-2H-1-Benzopyran)-2-Yl]-3,4,6-Trihydroxy-5H-Benzocyclohepten-5-One is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing including HPLC for purity, NMR and IR for structural confirmation, and residual solvent analysis to ensure compliance with research-grade specifications. Comprehensive Certificates of Analysis (COA) detailing 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 incompatible materials.
