Used as a key intermediate in the synthesis of quinolone antibiotics, particularly in the production of fluoroquinolone drugs which exhibit broad-spectrum antibacterial activity. Its structure allows for functionalization at multiple sites, enabling the development of derivatives with enhanced pharmacokinetic properties and improved efficacy against resistant bacterial strains. Also employed in medicinal chemistry research for the design of novel heterocyclic compounds with potential anticancer, antiviral, and anti-inflammatory activities. Its keto and ester functionalities make it suitable for condensation and coupling reactions in organic synthesis.
