Quality Control

Our Bis-(1,2-Dimethylcyclopentadienyl)-Zirconium Dichloride is manufactured under stringent quality protocols to ensure batch-to-batch consistency and high catalytic activity. Each lot is analyzed to confirm identity, purity, and absence of critical metallic impurities. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance and R&D documentation.

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 nature, the material should be handled under an inert atmosphere (argon or nitrogen) to prevent moisture absorption and degradation. Keep away from incompatible materials.
