Quality Control

Our Bis(3,5-Di-tert-Butylphenyl)Phosphine is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR, HPLC, and elemental analysis, to ensure high purity and consistency. Certificates of Analysis (COA) detailing lot-specific results are provided with every shipment to support your quality assurance and R&D documentation.

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 purged with inert gas after each opening to maintain product integrity.
