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 chloro and acetamido functional groups. Commonly employed in the development of antimicrobial, antifungal, and anti-inflammatory agents. Also utilized in agrochemical research for designing bioactive molecules with enhanced stability and selectivity.
