Used as an intermediate in the synthesis of dyes and pigments, particularly in the production of azo dyes due to its nitro and chloro functional groups that facilitate coupling reactions. It also serves in the preparation of pharmaceuticals where the chloronitrophenyl moiety is part of active molecules, especially in anti-inflammatory and antimicrobial agents. Additionally, it finds use in agrochemical synthesis, contributing to the development of certain herbicides and pesticides. Its reactivity makes it valuable in organic transformations, including nucleophilic substitution and reduction reactions to build more complex structures.
