m-Tolunitrile is primarily used as an intermediate in the synthesis of various organic compounds, particularly in the production of pharmaceuticals, agrochemicals, and dyes. Its nitrile group makes it a valuable precursor for the introduction of other functional groups through chemical reactions such as hydrolysis, reduction, or cyclization. In the pharmaceutical industry, it is employed in the development of active pharmaceutical ingredients (APIs) and other fine chemicals. Additionally, m-Tolunitrile finds application in the manufacturing of herbicides and pesticides, where it serves as a building block for creating compounds that target specific pests or weeds. Its versatility in organic synthesis also extends to the production of specialty chemicals and polymers, where it contributes to the development of materials with specific properties.
