Quality Control

Our 2,2-Bis(2-Hydroxy-5-Biphenylyl)Propane is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available upon request. We adhere to cGMP principles where applicable to support our customers in regulated industries.

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 sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from strong oxidizing agents.
