Quality Control

Our 2,3,4,4'-Tetrahydroxybenzophenone is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards and consistent specifications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles 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, well-ventilated area at room temperature (15-25°C). This material is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere); prolonged exposure to air, light, or elevated temperatures should be avoided to maintain stability and purity.
