Quality Control

Our Cyclopentadienylindenylzirconium Dichloride is manufactured under strict quality protocols to ensure batch-to-batch consistency and high catalytic activity. Each lot undergoes rigorous analytical testing, including NMR spectroscopy for structural confirmation and elemental analysis for purity verification. Certificates of Analysis (COA) detailing all specifications are available upon request to support your quality assurance and R&D documentation.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic and oxygen-sensitive nature, this material must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry place. Recommended long-term storage temperature is 2-8°C. The container should be kept tightly sealed in a secondary receptacle to minimize exposure to moisture and air.
