Used primarily as an intermediate in the synthesis of dyes and pigments, particularly in the production of azo dyes. It also serves in the manufacture of certain agricultural chemicals, including herbicides and insecticides. Due to the presence of both nitro and chloro groups, it is valuable in organic synthesis for further substitution reactions. Its derivatives are explored in the development of photochromic compounds and functional materials. Handling requires caution due to its potential toxicity and environmental impact.
