Used as an intermediate in the synthesis of antibacterial and antifungal agents, particularly in the development of quinolone-class antibiotics. It serves as a building block for modifying core structures to enhance biological activity and selectivity. Also employed in research for designing enzyme inhibitors and studying structure-activity relationships in medicinal chemistry. Its derivatives show potential in targeting DNA gyrase and topoisomerase IV, making them relevant in drug discovery for resistant microbial strains.
