Used as an intermediate in the synthesis of dyes and pigments, particularly in the production of azo dyes which are widely applied in the textile, printing, and coloring industries. It also serves in the manufacture of certain agrochemicals, including herbicides and pesticides, due to its reactivity in forming nitrogen-containing compounds. Additionally, it is employed in the development of pharmaceuticals where nitroaniline derivatives play a role in active ingredient synthesis. Its chloro and nitro functional groups allow for further chemical modifications, making it valuable in organic synthesis and research settings.
