Quality Control

Our Theaflavic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets high-grade specifications suitable for research and commercial use. Certificates of Analysis (COA) documenting full specifications 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 nature of being easily oxidized, long-term storage under an inert atmosphere (e.g., nitrogen or argon) is recommended for optimal stability.
