Quality Control

Our Rac-Ethylenebis(2-Methyl-1-Indenyl)Zirconium Dichloride is manufactured under strict quality protocols to ensure batch-to-batch consistency and high catalytic activity. Each lot is characterized using advanced analytical techniques to confirm identity, purity, and performance. Certificates of Analysis (COA) detailing specific parameters are provided with every shipment to support your quality assurance and R&D documentation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) at 2-8°C in a cool, dry place. This material is hygroscopic (moisture-sensitive) and easily oxidized. Allow the sealed container to reach ambient temperature before opening to minimize moisture condensation.
