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 explored in medicinal chemistry for anticancer and antiviral research due to its ability to intercalate with nucleic acids and modulate enzyme activity. Commonly employed in the preparation of complex heterocyclic compounds for pharmaceutical development.
