Quality Control

Our (1R,2R)-(+)-Bis(Methylphenylphosphino)Benzene is produced under strict quality management protocols to ensure batch-to-batch consistency and high chemical purity. Each lot undergoes comprehensive analysis, including chiral purity assessment by HPLC and spectroscopic identification. A Certificate of Analysis (COA) detailing specific results for purity, enantiomeric excess, and other critical parameters is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store under an inert atmosphere (argon or nitrogen) at 2-8°C. This compound is easily oxidized (store under inert atmosphere) and is light-sensitive (store away from light). Allow the container to reach ambient temperature before opening to minimize moisture condensation.
