  • Applications

    2,4-Dimethylaniline (CAS 95-68-1) is primarily used as an organic synthesis intermediate in the production of dyes and pigments, particularly azo dye chemistry, where it serves as a building block for azo coupling components. It is also employed as a precursor in the manufacture of specialty organic compounds for pharmaceutical and agrochemical intermediates. In the coatings, inks, and adhesives sectors, it can be used as a building block to generate colorants and functional additives. It may also be used in research and development settings as a precursor for new polymers or electronic materials, subject to local regulations and formulation limits.
