Quality Control

Our 6,6',7,7'-Tetrahydroxy-5,8'-Bi[2H-1-Benzopyran]-2,2'-Dione is produced under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity and spectroscopic identification (IR, NMR), to ensure it meets exacting standards for research and industrial use. Comprehensive Certificates of Analysis (COA) documenting all test results are 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 nature as an easily oxidized compound, long-term storage under an inert atmosphere (e.g., nitrogen or argon) is recommended for optimal stability. Keep away from strong oxidizing agents.
