Quality Control

Our Rac-Dimethylsilylbis-(1-Indenyl)Zirconium(Iv)Dimethyl is manufactured under stringent inert atmosphere conditions to ensure batch-to-batch consistency and high catalytic activity. Quality is verified through a comprehensive suite of analytical techniques including NMR spectroscopy and elemental analysis. A Certificate of Analysis (COA) detailing purity, identity, and performance-related parameters is provided with every shipment 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 (hygroscopic) and easily oxidized; therefore, handling must be performed in a controlled, dry, and oxygen-free environment.
