Quality Control

Our 1,2-Bis[(Z)-1-(Diphenylphosphino)Prop-1-Ylidene]Cyclohexane is manufactured under strict quality protocols to ensure batch-to-batch consistency and a minimum purity of 98%. Each lot is characterized by NMR (¹H, ³¹P) and HPLC analysis to confirm identity, isomeric purity, and chemical purity. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

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, the container should be purged with inert gas after each opening to minimize oxidation.
