Quality Control

Our Benzylidene-Bis(Tricyclohexylphosphine)Dichlororuthenium is manufactured and handled under strict quality protocols to ensure batch-to-batch consistency and high catalytic performance. Each lot undergoes comprehensive analytical testing, including NMR, HPLC, and elemental analysis, to confirm identity, purity, and the absence of deleterious impurities. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) in a cool, dry place. Recommended storage temperature is 2-8°C for long-term stability. This compound is easily oxidized and strictly light-sensitive; exposure to air or light will degrade its catalytic activity. Keep away from strong oxidizing agents.
