Quality Control

Our Bis(4,7-Dimethylindenyl)Zirconium Dichloride is manufactured under stringent conditions to ensure batch-to-batch consistency and high catalytic activity. Quality is verified through a comprehensive suite of analytical techniques, including NMR, elemental analysis (EA), and HPLC. A Certificate of Analysis (COA) detailing purity, isomeric composition, and other critical parameters is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and should be stored under an inert atmosphere (argon or nitrogen) in a cool, dry place. Recommended long-term storage temperature is 2-8°C. Allow the sealed container to reach room temperature before opening to prevent moisture condensation.
