Quality Control

Our Bis(Butylcyclopentadienyl)Tungsten Dichloride is produced and handled under strict quality protocols to ensure batch-to-batch consistency and reliability for sensitive applications. Each lot undergoes comprehensive analysis, including purity assay and identification. A Certificate of Analysis (COA) detailing specific results is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., argon or nitrogen) to prevent degradation.
