Quality Control

Our 2-(Diphenylphosphino)-Biphenyl is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and elemental analysis, to ensure high purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment to support your quality assurance and R&D documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its sensitivity to oxidation, containers should be purged with inert gas after each opening to maintain product integrity.
