Used as an intermediate in the synthesis of fluorescent dyes and optical brighteners for textiles and paper. Plays a role in the production of agrochemicals, particularly herbicides and fungicides, due to its reactivity and stability in chlorinated aromatic systems. Also employed in the development of sulfur-containing heterocyclic compounds for pharmaceutical research, especially in the design of antimicrobial and anti-inflammatory agents. Its nitro and chloro functional groups allow for sequential substitution reactions, making it valuable in fine chemical synthesis and material science applications.
