Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of sulfonamide antibiotics. It plays an important role in constructing heterocyclic frameworks found in biologically active molecules. Its functional groups enable coupling reactions and cyclizations, making it valuable in medicinal chemistry for developing drugs with antimicrobial and anti-inflammatory properties. Also employed in agrochemical research for designing novel pesticides and herbicides due to its reactivity and structural features.
