Quality Control

Our 1,2-Bis(Diphenylphosphino)Ethane 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 all specifications are provided with every shipment. We are committed to meeting the stringent requirements of research and industrial applications.

Storage

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