Quality Control

Our Bis[(2-Diphenylarsinoethyl)Phenyl]Phosphine is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including NMR (¹H, ³¹P), HPLC for purity assessment, and elemental analysis to confirm identity and composition. Certificates of Analysis (COA) detailing all specifications are available upon request to ensure full traceability and compliance with your research or development requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at a 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 glovebox or under a positive pressure of inert gas.
