Quality Control

Our cis-1,2-Bis(Diphenylphosphino)Ethylene is manufactured under strict quality protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including NMR, HPLC, and elemental analysis. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee compliance with your research and production requirements.

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 before resealing after each use.
