Quality Control

Our 5-Hydroxy-3,4-Bis(4-Hydroxyphenyl)-7-Phenyl-2,6-Benzofurandione is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and spectroscopic identification (IR, NMR), to ensure it meets precise customer specifications and high industry standards. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from incompatible materials.
