  • Applications

    N,N-dimethyl-m-toluidine (CAS 121-72-2) is a tertiary aromatic amine used primarily as an intermediate and catalyst in polyurethane systems, particularly for foams, coatings, and adhesives. It is also employed as a building block in the synthesis of specialty polymers and plastics and may participate in curing and processing in epoxy/polyurethane formulations used in coatings and electronics. In addition, it serves as an intermediate in dye and pigment chemistry, and can be used as a solvent or reaction medium in certain organic syntheses. Owing to its basicity and reactivity, it is commonly evaluated as a component of catalyst systems or intermediates, with use subject to local regulations and formulation limits.
