Used as a key intermediate in the synthesis of quinolone-based pharmaceuticals, particularly in the development of antibacterial and antiviral agents. Its structure supports the formation of compounds with potent biological activity by serving as a building block for modifying the quinoline core. Commonly employed in medicinal chemistry for structure-activity relationship studies to enhance drug efficacy and selectivity. Also utilized in research settings to develop novel kinase inhibitors and anti-inflammatory agents due to its ability to interact with biological targets through hydrogen bonding and aromatic interactions.
