Used as an intermediate in the synthesis of sulfonamide antibiotics, particularly in the production of thiazole-based antimicrobial agents. It plays a key role in the development of pharmaceuticals due to its reactive amino and chloro functional groups, which allow for further chemical modifications. Commonly employed in the preparation of dyes, agrochemicals, and biologically active compounds, including kinase inhibitors and antitumor agents. Its structure supports conjugation in heterocyclic systems, making it valuable in medicinal chemistry and drug design.
