Used as a key intermediate in the synthesis of quinolone-based pharmaceuticals, particularly in the development of antibiotics and antiviral agents. Its structure supports the formation of bioactive molecules with potent antimicrobial properties. Commonly employed in medicinal chemistry for constructing fused quinoline systems that exhibit enhanced binding to DNA gyrase and topoisomerase enzymes. Also utilized in research settings to design novel heterocyclic compounds with potential anticancer and anti-inflammatory activities.
