Quality Control

Our Rac-Dimethylsilylenebis(2-Methylindenyl)Dimethylzirconium is manufactured under stringent inert atmosphere conditions to ensure purity and catalytic activity. Each batch is characterized by advanced analytical techniques including NMR and elemental analysis to confirm identity and composition. Certificates of Analysis (COA) detailing batch-specific results are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) at temperatures between 2°C and 8°C (refrigerated) to maintain stability and prevent decomposition. This compound is moisture-sensitive and easily oxidized; therefore, handling must be performed in a controlled, dry, and oxygen-free environment.
