Quality Control

Our Meso-Dimethylsilylenebis(2-Methyl-1-Indenyl)Zirconium(IV) Dichloride is manufactured under stringent conditions to ensure batch-to-batch consistency and high catalytic performance. Each lot undergoes rigorous analytical testing, including NMR and elemental analysis, to verify identity and purity. Certificates of Analysis (COA) documenting all critical specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-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. Allow the container to reach room temperature before opening to prevent moisture condensation.
