m-Nitroaniline is primarily used as an intermediate in the synthesis of azo dyes, which are widely employed in the textile, leather, and paper industries to produce vibrant and long-lasting colors. It also serves as a precursor in the manufacture of various organic compounds, including pharmaceuticals and agrochemicals, due to its nitro and amino functional groups that facilitate further chemical modifications. Additionally, m-Nitroaniline is utilized in research and development for studying chemical reactions and mechanisms, particularly in organic synthesis. Its role in the production of corrosion inhibitors and rubber chemicals further highlights its industrial significance.
