Quality Control

Our 2,2μ Bis(Diphenylphosphino)Benzophenone is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including NMR, HPLC, and elemental analysis, to ensure high purity and consistency for sensitive catalytic applications. Certificates of Analysis (COA) detailing all specifications are available upon request, supporting your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at controlled room temperature (15-25°C) in a cool, dry, and well-ventilated place. Due to its sensitivity to oxidation, the container should only be opened in an inert environment.
