Description

Dimethylsilylbis-(4,5,6,7-Tetrahydro-1-Indenyl)Zirconium(IV)-(R)-(1,1'-Binaphthyl-2) is a highly specialized, chiral ansa-metallocene complex of zirconium, serving as a sophisticated single-site catalyst precursor. Its value lies in enabling precise stereochemical control during olefin polymerization, which is critical for producing polymers with tailored microstructures and superior physical properties. This compound is essential for R&D chemists and process engineers in the advanced polyolefin, specialty polymer, and fine chemical synthesis sectors, particularly for developing novel isotactic or syndiotactic polymers.

Application

• Stereospecific Olefin Polymerization: As a key catalyst component for the synthesis of isotactic polypropylene (iPP) and other stereoregular polyolefins.
• Advanced Polymer R&D: For investigating new polymerization mechanisms and developing polymers with specific tacticity, molecular weight, and comonomer incorporation.
• Fine Chemical Synthesis: Utilized as an asymmetric catalyst or catalyst precursor in certain organic transformations requiring zirconium-mediated C-C bond formation.
• Catalyst Ligand Development: Serves as a benchmark or starting material for designing new generations of chiral metallocene ligands and complexes.
• Material Science: Enables the production of specialty polymeric materials with enhanced clarity, impact strength, or thermal properties for high-performance applications.

Quality Control

Every batch of our metallocene catalysts undergoes rigorous analytical characterization to ensure identity, purity, and catalytic performance. We provide a comprehensive Certificate of Analysis (COA) with each shipment, detailing key parameters such as chiral purity, zirconium content, and solvent residues. Our quality system is designed to support cGMP and ISO 9001 standards for traceability and consistency, which is critical for reproducible polymerization research and process development.

Storage

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