Quality Control

Our 2-(2,5-Dihydroxy-4-Methoxyphenyl)-3,5,6,7-Tetramethoxy-4H-1-Benzopyran-4-One is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR 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 light-sensitive nature and propensity to be easily oxidized, long-term storage under an inert atmosphere (e.g., nitrogen or argon) in a freezer (-20°C) is recommended for optimal stability.
