Used as an 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 antimicrobial properties. Also employed in research for designing novel heterocyclic compounds with potential therapeutic activity. Shows utility in medicinal chemistry for optimizing drug candidates targeting DNA gyrase and topoisomerase enzymes. Additionally, serves as a building block in the preparation of fluorescent probes and dyes due to its conjugated aromatic system.
