  • Applications

    1,3-Dimethylbutylamine (CAS number: 108-09-8) is a versatile chemical intermediate used as a building block for amine-functional derivatives in pharmaceutical and agrochemical development. It can serve as a precursor for further derivatization (e.g., amide formation and other functional transformations). In the polymers and coatings sector, it may act as a reactive amine component in epoxy and polyurethane systems, serving as a curing or crosslinking agent and supporting formulation of specialty coatings and adhesives. In addition, it may be used as a starting material for the synthesis of specialty chemicals and industrial additives, depending on formulation needs and local regulatory requirements.
