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 antiviral and anticancer agents due to its ability to interact with biological targets through hydrogen bonding and aromatic interactions. Employed in research settings to design new bioactive molecules with improved pharmacokinetic properties.
