Quality Control

Our 3,5,7-Trihydroxychromone is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, IR and MS for structural confirmation, and residual solvent analysis. We provide a detailed Certificate of Analysis (COA) with every shipment to ensure traceability and compliance with your research or production 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 sensitivity to oxidation, prolonged storage under an inert atmosphere (e.g., nitrogen or argon) is recommended for optimal long-term stability. Keep away from strong oxidizing agents.
