m-Nitrotoluene is primarily used as an intermediate in the synthesis of various chemicals, particularly in the production of dyes and pigments. It serves as a key starting material for the manufacture of m-toluidine, which is further utilized in creating azo dyes. These dyes are widely applied in the textile, paper, and leather industries for coloring purposes. Additionally, m-Nitrotoluene is employed in the production of agricultural chemicals, including pesticides and herbicides, due to its role in forming complex organic compounds. It also finds use in the pharmaceutical industry for synthesizing certain active ingredients in drugs. In research and development, it acts as a reagent for organic synthesis, aiding in the creation of novel compounds.
