Quality Control

Our 3',5,5',7-Tetrahydroxyflavane is manufactured under strict quality management systems. Each batch is subjected to comprehensive analytical testing, including identity confirmation by IR and NMR, purity assessment by HPLC, and residual solvent analysis to ensure it meets stringent specifications for research and development use. A Certificate of Analysis (COA) detailing all test results is 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, it is recommended to store the product under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep the container tightly sealed in a dry environment to minimize moisture exposure.
