Used as a key intermediate in the synthesis of various pharmaceuticals, particularly in the production of thiazole-based drugs with antimicrobial, antiviral, and anti-inflammatory properties. It serves as a building block in the development of sulfathiazole derivatives and other heterocyclic compounds important in medicinal chemistry. Its reactive functional groups enable easy modification for creating libraries of compounds in drug discovery. Also employed in the preparation of agrochemicals and dyes due to its stable heterocyclic structure and reactivity.
