Used as a key intermediate in the synthesis of quinolone antibiotics, particularly in the production of fluoroquinolone-class antimicrobial agents. Its structure allows for the formation of the core quinolone ring system, which is essential for the biological activity of these drugs. It is employed in pharmaceutical research and development to create derivatives with enhanced antibacterial properties, improved pharmacokinetics, and reduced side effects. The compound is also explored in medicinal chemistry for its potential in developing new treatments against resistant bacterial strains.
