  • Applications

    2-Octylamine (CAS 693-16-3) is a primary amine with an eight-carbon chain used as an intermediate for surfactant derivatives, including alkylamine-based cationic surfactants employed in household and industrial cleaners. It also serves as a building block for imidazoline-type corrosion inhibitors used in metal protection and water treatment. In polymer and coatings, it acts as a reactive amine component in polyurethane and polyurea formulations, enabling coatings and adhesives. Additionally, it is an intermediate for the synthesis of agrochemicals and pharmaceutical intermediates.
