Used as a key intermediate in the synthesis of various pharmaceuticals, particularly in the production of sulfathiazole and other sulfonamide antibiotics. Plays a role in the development of agrochemicals, including certain fungicides and plant growth regulators. Employed in research for the preparation of heterocyclic compounds with potential biological activity, such as kinase inhibitors and antimicrobial agents. Its structure serves as a building block in medicinal chemistry for designing new drug candidates targeting inflammation, cancer, and infectious diseases. Additionally, it is used in the synthesis of ligands for transition metal complexes in catalytic applications.
