Quality Control

Our production of 4,9-Etheno-1H-Benz[F]Isoindole-1,3(2H)-Dione, 3A,4,9,9A-Tetrahydro-10-Hydroxy-2-(4-Hydroxyphenyl)- adheres to a rigorous quality management system. Each batch is analytically verified using techniques such as HPLC, NMR, and mass spectrometry to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to support your quality assurance and regulatory needs.

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, long-term storage under an inert atmosphere (e.g., nitrogen or argon) is recommended for optimal stability. Keep away from incompatible materials such as strong oxidizing agents.
