Used as a key intermediate in the synthesis of quinolone-based pharmaceuticals, particularly in the development of antimicrobial and antiviral agents. Its hydroxy-substituted quinoline structure enables coordination with metal ions, making it useful in the design of fluorescent sensors and bioimaging probes. Also employed in research for developing novel kinase inhibitors due to its ability to interact with ATP-binding sites in enzymes. Shows potential in materials science for creating organic semiconductors owing to its conjugated aromatic system and electron-accepting properties.
