Quality Control

Our production of Bis[Bis(3,5-Dimethylphenyl)Phosphino]Methane adheres to stringent quality protocols to ensure batch-to-batch consistency and high catalytic performance. Each lot undergoes comprehensive analysis, including NMR (¹H, ³¹P) and HPLC purity verification. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting all critical specifications. We support compliance with REACH and other relevant global regulatory frameworks.

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, the container should only be opened in an inert glovebox or under a positive pressure of inert gas.
