Used as a key intermediate in the synthesis of fluoroquinolone antibiotics, enhancing antimicrobial activity against a broad spectrum of bacteria. Its structure supports the development of drugs targeting DNA gyrase and topoisomerase IV, critical for bacterial replication. Also employed in research for developing new pharmaceuticals with improved pharmacokinetics and resistance profiles. Shows potential in agrochemicals for crop protection due to its bioactive scaffold. Used in fluorescence-based assays and sensors owing to its photophysical properties.
