Quality Control

Our (1R,2R)-(+)-Bis(Methylphenylarsino)Benzene is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chiral purity analysis by HPLC and identity confirmation by spectroscopic methods, to ensure it meets the high standards required for research and development applications. Certificates of Analysis (COA) detailing purity, enantiomeric excess, and other critical parameters are available upon request.

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 be kept sealed under positive pressure of inert gas when not in use.
