Quality Control

Our Bis(Butylcyclopentadienyl)Tungsten Diiodide is manufactured under controlled conditions to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including NMR and elemental analysis, to verify identity and composition. A Certificate of Analysis (COA) detailing all quality parameters is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) at room temperature (15-25°C) in a cool, dry, and well-ventilated place. This material is moisture-sensitive and easily oxidized; containers must be kept sealed and handled under inert conditions to prevent degradation.
