Used as a key intermediate in the synthesis of thiazole-based pharmaceuticals, particularly in the production of sulfathiazole and other sulfonamide antibiotics. It plays an important role in constructing heterocyclic frameworks in medicinal chemistry due to its reactive amino and carbonyl groups. Also employed in the development of agrochemicals and bioactive molecules with antimicrobial and antifungal properties. Its structure allows for easy functionalization, making it valuable in drug discovery and combinatorial chemistry.
