Quality Control

Our 1,4-Bis(Dicyclohexylphosphino)Butane is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including NMR, HPLC, and elemental analysis. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory needs.

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 area. Due to its sensitivity to oxidation, containers should be kept sealed and only opened in an inert environment.
