Quality Control

Our Dicyclohexyl(2-Methylphenyl)Phosphine is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including NMR (¹H, ³¹P), HPLC, and GC analysis, to ensure high purity and consistency. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available for every shipment to support your quality assurance protocols.

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.
