Quality Control

Every batch of 3,3-Bis(4-Hydroxy-3-Phenyl-Phenyl)Isobenzofuran-1-One undergoes rigorous analytical testing to ensure identity, purity, and consistency. Our quality assurance protocols are designed to meet the stringent requirements of industrial and research applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its light-sensitive nature and propensity to be easily oxidized, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from strong oxidizing agents.
