Quality Control

Our Bis[(2-Diphenylphosphino)Ethyl]Ammonium Chloride is produced under strict quality management protocols. Every batch undergoes rigorous analytical testing, including NMR, HPLC, and elemental analysis, to ensure it meets the specified minimum 97% purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place at 15-25°C. Due to its hygroscopic and easily oxidized nature, the container should only be opened in a controlled, moisture-free environment and resealed immediately after use.
