Quality Control

Our 2,2',3,3'-Tetrahydro-2,2',5,5'-Tetrahydroxy-6,6',8,8'-Tetramethoxy-2,2'-Dimethyl-7,10'-Bi[4H-Naphtho[2,3-B]Pyran]-4,4'-Dione is produced under strict quality management protocols. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and MS, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided and available upon request to support your quality assurance and regulatory needs.

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 prevent moisture absorption.
