Quality Control

Our Dimethylsilylbis(Cyclopentadienyl)Zirconium Dichloride is manufactured under stringent conditions to ensure batch-to-batch consistency and high catalytic activity. Every lot undergoes comprehensive analytical testing, including NMR, elemental analysis, and HPLC, to verify identity, purity, and the absence of detrimental impurities. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting all critical quality parameters.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic nature, this material should be handled and stored under an inert atmosphere (argon or nitrogen) to prevent moisture absorption and decomposition. Recommended long-term storage temperature is 2-8°C.
