CAS 100-99-2 — Triisobutylaluminium

Triisobutylaluminium is an organoaluminium compound widely used as a catalyst in polymerization reactions, particularly in the production of high-density polyethylene and other synthetic polymers. It is also employed in organic synthesis for alkylation and isomerization processes. This clear, colorless liquid is highly reactive with air and moisture, requiring careful handling under inert conditions. Triisobutylaluminium has a CAS number of 100-99-2, with the molecular formula C12H27Al and a molecular weight of 198.3243 g/mol. It is typically stored at ambient temperatures in sealed containers under nitrogen or argon. The substance carries no signal word under standard classification but demands strict exclusion of oxygen and water to prevent hazardous reactions. Molekula supplies Triisobutylaluminium from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
