Quality Control

Our Theaflavin 3,3′-Digallate is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity verification and identity confirmation by spectroscopic methods, to ensure it meets the high standards required for research and industrial use. Certificates of Analysis (COA) detailing purity, impurities, and other critical parameters are available upon request.

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 for long-term preservation. Keep the container tightly sealed in a dry environment to minimize exposure to moisture.
