Description

Rac-Dimethylsilylbis(1-Indenyl)Zirconium Dichloride CAS NO 121009-93-6 is a highly active and versatile metallocene catalyst precursor, specifically a bridged bis(indenyl) zirconocene dichloride complex. This compound is a critical component for the production of advanced polyolefins, enabling precise control over polymer microstructure and properties. It is essential for R&D and manufacturing in the polymer and specialty chemicals industries, particularly for developing novel polypropylene and polyethylene grades with tailored performance characteristics.

Application

• Catalyst Component for Polyolefin Polymerization: Primary use as a single-site catalyst precursor for the production of isotactic polypropylene (iPP) and linear low-density polyethylene (LLDPE).
• Advanced Material Synthesis: Enables the synthesis of polymers with controlled tacticity, molecular weight, and comonomer incorporation for high-performance applications.
• Polymer R&D: A key reagent in academic and industrial research for studying structure-activity relationships in metallocene catalysis and developing new polymerization processes.
• Specialty Elastomers and Plastomers: Used in catalyst systems for producing ethylene-propylene rubbers (EPR/EPDM) and other elastomeric polyolefins.
• Olefin Oligomerization: Can be activated for selective olefin oligomerization reactions to produce valuable chemical intermediates.

Quality Control

Our Rac-Dimethylsilylbis(1-Indenyl)Zirconium Dichloride is manufactured under stringent conditions to ensure high catalytic activity and batch-to-batch consistency. Each lot undergoes rigorous analytical testing, including NMR spectroscopy and elemental analysis, to confirm identity and purity. Certificates of Analysis (COA) detailing specific lot 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 and moisture-sensitive nature, this material must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry place. Recommended storage temperature is 2-8°C for long-term stability. Handle and open containers only in a controlled, moisture-free environment.
