Description

(2,3-Bis-(2,6-Di-Isopropylphenyl-Imino)-Butane)-Nickel(II)-Dibromide is a highly specialized organonickel complex, recognized as a high-performance catalyst precursor. This compound matters for its critical role in facilitating precise and efficient polymerization and oligomerization reactions, enabling the production of advanced polymeric materials. It is primarily needed by R&D chemists and process engineers in the petrochemical and advanced materials sectors for developing novel polymers and fine chemicals.

Application

• Catalyst Precursor for Olefin Polymerization: A key component in the synthesis of polyolefins, including polyethylene and polypropylene, with controlled molecular weight and tacticity.
• Oligomerization of Ethylene & α-Olefins: Used to produce linear α-olefins (LAOs) and other valuable oligomers for surfactants, plasticizers, and synthetic lubricants.
• Catalyst in Fine Chemical Synthesis: Enables selective C-C and C-heteroatom bond-forming reactions in the synthesis of complex organic molecules and pharmaceutical intermediates.
• Material Science Research: Employed in academic and industrial R&D for developing new catalytic systems and functional polymeric materials.
• Co-catalyst Systems: Often activated with aluminum alkyls or other co-catalysts (e.g., MAO, MMAO) to form highly active catalytic species for polymerization.

Quality Control

Our (2,3-Bis-(2,6-Di-Isopropylphenyl-Imino)-Butane)-Nickel(II)-Dibromide is manufactured under stringent quality protocols. Every batch undergoes rigorous analytical testing to ensure high purity, consistent catalytic activity, and batch-to-batch reproducibility. Comprehensive Certificates of Analysis (COA) detailing identity, purity, and residual solvent content are provided to support your R&D and production quality assurance.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C) in a cool, dry, and well-ventilated place. This material is moisture-sensitive and easily oxidized; prolonged exposure to air or humidity must be avoided to maintain catalytic efficacy.
