Used as an intermediate in the synthesis of fluorescent dyes and optical brighteners due to its ability to undergo nucleophilic substitution and reduction reactions. Its nitro and chloro functional groups allow for selective modifications, making it valuable in the development of dyes for textiles, paper, and plastics. Also employed in the preparation of bioactive compounds and pharmaceuticals, particularly in the design of agents with antimicrobial or anti-inflammatory properties. Additionally, it serves as a building block in the synthesis of phthalimide-based derivatives used in material science and agrochemicals.
