  • Applications

    2-Methylaminoethanol (CAS 109-83-1) is widely used as an intermediate and solvent in industrial manufacturing. It serves as a building block for cationic and nonionic surfactants and wetting agents, and functions as a reactive diluent in coatings and inks. It is also a precursor for polyurethane and epoxy resin formulations, acting as a base or curing component and as a processing additive in polymer systems. Additionally, it is used in adhesive formulations to modify properties and as a solvent/additive in specialty cleaners and metalworking fluids. Use is subject to local regulations and formulation limits.
