Quality Control

Our Cinnamtannin B-1 is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity verification, to ensure it meets the high standards required for research and industrial use. Certificates of Analysis (COA) detailing specific batch results 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, the material should be kept under an inert atmosphere to prevent oxidation. Keep the container tightly sealed in a dry environment to minimize moisture exposure.
