Used as an intermediate in the synthesis of quinolone antibiotics, particularly in the development of fluoroquinolone-class antimicrobial agents. Its structure supports the construction of pharmacologically active compounds targeting bacterial DNA gyrase and topoisomerase IV. Commonly employed in medicinal chemistry for optimizing antimicrobial potency and spectrum of activity. Also utilized in research settings for developing novel heterocyclic compounds with potential antitumor, antiviral, or anti-inflammatory properties.
