Description

Dibromoethylaluminium is a highly reactive organoaluminium compound primarily used as a versatile alkylating and polymerization catalyst. Its value lies in its ability to facilitate efficient carbon-carbon bond formation and initiate specific polymerization reactions under controlled conditions. This chemical is essential for researchers and manufacturers in the pharmaceutical, specialty chemical, and advanced materials sectors who require precise and powerful reagents for synthesis and catalysis.

Application

• As a key cocatalyst or activator in Ziegler-Natta type olefin polymerization systems.
• Employed in organic synthesis as an ethylation or alkylation reagent for introducing ethyl groups.
• Used in the production of fine chemicals and pharmaceutical intermediates requiring aluminum-mediated transformations.
• Serves as a precursor or reagent in material science research for developing novel organometallic compounds and catalysts.
• Acts as a Lewis acid catalyst in various condensation and coupling reactions.
• Applied in specialty polymer manufacturing to control polymer architecture and molecular weight.

Quality Control

Our Dibromoethylaluminium is manufactured under stringent controls to ensure batch-to-batch consistency and high reactivity. Quality is verified through a suite of analytical techniques including titration, gas chromatography (GC), and spectroscopic methods. A Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each 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) in a cool, dry, and well-ventilated area, away from moisture, heat, and incompatible materials. Due to its pyrophoric and moisture-sensitive nature, handling must be conducted under inert conditions using appropriate safety equipment.
