Quality Control

Our Bis(Ethylcyclopentadienyl)Tungsten Dichloride is manufactured under strict quality protocols to ensure batch-to-batch consistency and high purity for demanding applications. Each lot is analyzed to confirm identity, purity, and impurity profiles. Certificates of Analysis (COA) detailing specific results are provided and can be tailored to meet customer-specific requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., argon or nitrogen) in a cool, dry, and well-ventilated place. Due to its moisture-sensitive and easily oxidized nature, the container should be kept sealed and handled in a controlled environment to maintain product integrity. Recommended long-term storage temperature is 2-8°C.
