Used primarily as an intermediate in the synthesis of pharmaceuticals and agrochemicals. It plays a key role in the preparation of sulfonamide derivatives, which are important in the development of active ingredients in certain drugs, including antimicrobial and anti-inflammatory agents. Its reactive chloro and nitro groups facilitate further chemical modifications, making it valuable in organic synthesis and medicinal chemistry research. Also employed in the production of dyes and functionalized aromatic compounds for specialized industrial applications.
