Used as an intermediate in the synthesis of dyes and pigments, particularly in the production of reactive dyes for cotton and other cellulosic fibers. It plays a key role in the development of azo and anthraquinone-based colorants due to its ability to undergo nucleophilic substitution reactions. Also employed in the preparation of pharmaceuticals and agrochemicals, where the nitro and chloro functional groups allow for further chemical modifications. Its reactivity makes it valuable in the construction of heterocyclic compounds used in research and industrial applications.
