Description

Dichlorobis(2-Methylindenyl)Hafnium CAS NO 352545-70-1 is a highly specialized organometallic compound belonging to the class of metallocene catalysts. This compound is of significant industrial importance as a single-site catalyst precursor for the polymerization of olefins, enabling the production of polymers with highly controlled molecular weight and stereoregularity. It is primarily required by advanced chemical manufacturers and R&D facilities in the petrochemical and polymer industries for the development of high-performance polyolefin materials.

Application

• Precursor for single-site catalysts in the polymerization of ethylene and propylene.
• Key component in the synthesis of high-density polyethylene (HDPE) and linear low-density polyethylene (LLDPE) with tailored properties.
• Used in the development of stereospecific polyolefin elastomers (POE) and plastomers.
• Critical for advanced materials research in catalyst design and polymer science.
• Employed in specialty chemical synthesis as an organohafnium reagent.
• Facilitates the production of polymers with enhanced mechanical strength, clarity, and processability.

Quality Control

Our Dichlorobis(2-Methylindenyl)Hafnium is manufactured under stringent conditions to ensure high purity and batch-to-batch consistency, critical for catalytic performance. Each lot undergoes comprehensive analytical testing, including NMR, elemental analysis, and purity assay. A Certificate of Analysis (COA) detailing all specifications 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 room temperature (15-25°C) in a cool, dry, and well-ventilated area. This material is moisture-sensitive (hygroscopic) and easily oxidized; exposure to air and humidity must be minimized to maintain stability and efficacy.
