Quality Control

Our 1,2-Bis(Dichlorophosphino)Benzene is manufactured under strict quality protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including NMR, GC, and elemental analysis, to verify identity and purity against established specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) in a cool, dry, and well-ventilated place. Due to its moisture-sensitive and easily oxidized nature, the container should be kept sealed and handled under inert conditions to maintain product integrity. Recommended storage temperature is 2-8°C for long-term stability.
