Used as a key intermediate in the synthesis of quinolone-based pharmaceuticals, particularly in the production of fluoroquinolone antibiotics. Its structure supports the formation of core quinolone rings essential for antimicrobial activity. Commonly employed in research and development for novel antibacterial agents due to its reactivity and functional groups that allow for further chemical modifications. Also utilized in medicinal chemistry for structure-activity relationship studies to enhance drug potency and reduce side effects.
