Quality Control

Our 1,2-Bis(Di-2-Pyridylphosphino)Ethane is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC, NMR, and elemental analysis, to confirm identity and meet the specified minimum 98% purity. A Certificate of Analysis (COA) detailing all test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Due to its sensitivity to oxidation, long-term storage under an inert atmosphere (argon or nitrogen) is strongly recommended. Store in a cool, dry place at a controlled room temperature (15-25°C). Keep away from strong oxidizing agents.
