Quality Control

Our Dicyclohexyl-(p-Tolyl)-Phosphine is manufactured under strict quality management protocols. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and elemental analysis, to ensure the purity exceeds 98% and meets the stringent requirements for catalytic applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to guarantee traceability and consistency for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Due to its sensitivity to oxidation, this material should be stored under an inert atmosphere (argon or nitrogen) in a cool, dry place. Recommended storage temperature is 2-8°C for long-term stability. Keep the container tightly sealed when not in use to minimize exposure to air and moisture.
