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 drugs with enhanced activity against resistant bacterial strains. Commonly employed in pharmaceutical research to improve potency, pharmacokinetics, and spectrum of action in new quinolone-based therapeutics. Also utilized in the preparation of compounds targeting DNA gyrase and topoisomerase IV, critical enzymes in bacterial DNA replication.
