Quality Control

Our 1,5-Bis(Diphenylphosphino)Octane is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including NMR, HPLC, and elemental analysis, to ensure high chemical purity and consistent performance. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles are available upon request 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 a controlled room temperature (15-25°C) in a cool, dry, and well-ventilated area. Due to its sensitivity to oxidation, containers should be purged with inert gas after each opening to maintain product integrity.
