Quality Control

Our Rac-Dimethylsilylenebis(4,5,6,7-Tetrahydro-1-Indenyl)Zirconium(Iv) Dichloride is manufactured under strict quality protocols to ensure batch-to-batch consistency and high catalytic activity. All materials undergo rigorous analytical testing, including NMR spectroscopy and elemental analysis, to verify identity and purity. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical characteristics is provided with each shipment to support your quality assurance and process validation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) at a controlled room temperature (15-25°C) in a cool, dry, and well-ventilated place. This material is moisture-sensitive (hygroscopic) and easily oxidized; therefore, containers must be kept sealed and handled under an inert environment to maintain stability and catalytic performance.
