  • Applications

    Diisobutylamine (CAS 110-96-3) is primarily used as a chemical intermediate and building block in the synthesis of specialty chemicals. It is commonly used to prepare carbamate and urea derivatives for pharmaceutical and agrochemical applications. It can serve as a base or co-catalyst in polyurethane and epoxy resin formulations, aiding curing and processing. It may also function as a solvent or reaction medium in certain industrial processes. In coatings and inks, it is sometimes employed as a processing additive to influence cure behavior and film formation. Additionally, it is used as a starting material in cleaning formulations and in metalworking fluids as a basic amine additive. All uses are subject to local regulations and formulation limits.
