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 bioactive molecules by serving as a building block for further functionalization at the 6- and 3-positions. Commonly employed in medicinal chemistry for constructing fused heterocyclic systems with potential CNS activity. Also utilized in research for developing novel kinase inhibitors and anti-inflammatory compounds due to its ability to interact with biological targets through hydrogen bonding and aromatic interactions.
