Quality Control

Our Bis(Cyclopentadienyl)Tungsten Dihydride is produced and handled under stringent inert atmosphere conditions to ensure purity and stability. Each batch undergoes rigorous analytical testing, including NMR spectroscopy and elemental analysis, to verify chemical identity and composition. A Certificate of Analysis (COA) detailing specific lot results is provided with every shipment to guarantee compliance with your research or production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) at temperatures between 2°C and 8°C (refrigerated) to minimize decomposition. This material is hygroscopic (moisture-sensitive) and easily oxidized; therefore, it must be handled exclusively in a controlled, moisture-free, and oxygen-free environment.
