Used as a key intermediate in the synthesis of fluoroquinolone antibiotics, particularly in the production of advanced antimicrobial agents. Its structure supports the development of compounds with enhanced activity against resistant bacterial strains. Commonly employed in pharmaceutical research to build the core scaffold of quinolone-based drugs, improving potency and pharmacokinetic properties. Also utilized in the development of novel therapeutic agents targeting DNA gyrase and topoisomerase IV enzymes in pathogenic microorganisms.
