Description

Rac-Ethylenebis-(4,5,6,7-Tetrahydro-1-Indenyl)-Difluorozirconium(IV) is a highly specialized metallocene catalyst component, specifically a zirconocene dichloride derivative, essential for advanced polyolefin synthesis. Its primary value lies in enabling precise control over polymer stereochemistry and molecular weight, which is critical for producing high-performance materials with tailored properties. This compound is a key raw material for R&D chemists and process engineers in the polymer and advanced materials industries, particularly for developing novel catalysts for the production of syndiotactic polypropylene and other stereoregular polymers.

Application

• Catalyst Component for Polyolefin Polymerization: Serves as a single-site catalyst precursor for the synthesis of stereoregular polypropylene (e.g., syndiotactic) and polyethylene.
• Advanced Materials R&D: Used in research laboratories to develop and test new metallocene catalyst systems with specific activity and selectivity profiles.
• Specialty Polymer Production: Enables the manufacture of polymers with controlled microstructures for applications requiring specific mechanical, thermal, or optical properties.
• Co-catalyst Systems: Activated with methylaluminoxane (MAO) or other co-catalysts to form the active catalytic species for olefin polymerization.
• Fine Chemical Synthesis: May be employed as an intermediate or reagent in organometallic synthesis and asymmetric catalysis research.

Quality Control

Our products undergo rigorous quality testing to ensure batch-to-batch consistency and compliance with stringent industry standards for catalyst precursors. Each lot is characterized using advanced analytical techniques to confirm identity, purity, and the absence of detrimental impurities. A comprehensive Certificate of Analysis (COA) detailing specifications such as zirconium content, fluorine content, and solvent residues 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 a controlled room temperature (15-25°C) in a cool, dry, and well-ventilated place. Due to its moisture-sensitive and easily oxidized nature, the container must be kept tightly sealed and handled under inert conditions to maintain product integrity.
