Used as a key intermediate in the synthesis of fluoroquinolone antibiotics, which are broad-spectrum antimicrobial agents. It contributes to the core structure that enhances drug potency against bacterial DNA gyrase and topoisomerase IV. Also explored in medicinal chemistry for developing novel anticancer and antiviral compounds due to its ability to intercalate into nucleic acids and modulate enzyme activity. Its fluorinated aromatic system improves metabolic stability and bioavailability in pharmaceutical formulations.
