Quality Control

Our 1,2-Bis(Diphenylarsino)Ethane is produced and handled under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC and NMR analysis, to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your research or production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Recommended long-term storage temperature is 2-8°C. Due to its sensitivity, the container should be kept tightly sealed and allowed to reach room temperature before opening to minimize moisture ingress and oxidation.
