Used as an intermediate in the synthesis of nitrofuran antibiotics, which exhibit broad-spectrum antimicrobial activity against bacteria and protozoa. Commonly employed in the development of pharmaceuticals for treating urinary tract infections and gastrointestinal infections. Also serves as a building block in organic synthesis for heterocyclic compounds with potential biological activity. Its α,β-unsaturated aldehyde structure allows for Michael addition and cyclization reactions, making it valuable in medicinal chemistry research.
