  • Applications

    Dibutylamine (CAS 111-92-2) is primarily used as a chemical intermediate and building block in organic synthesis. It serves as a precursor for quaternary ammonium salts and other amine derivatives, and is used in the production of surfactants, lubricants, and rubber additives. It can function as a reactive amine in epoxy resin formulations, acting as a curing agent or co-curing component, and may be used as a processing solvent or diluent in certain manufacturing steps. In polymer and coating formulations, it helps modify formulation properties and can influence processing behavior. Its role is that of an intermediary in industrial manufacturing, with use subject to local regulations and formulation limits.
