Used as a key intermediate in the synthesis of quinolone-based pharmaceuticals, particularly in the development of antibacterial and antiviral agents. Its structure allows for further functionalization at the bromine site, enabling the formation of carbon-carbon and carbon-heteroatom bonds. Commonly employed in medicinal chemistry for constructing fused heterocyclic systems. Also utilized in research settings to develop kinase inhibitors and other biologically active molecules due to its ability to mimic natural heterocyclic scaffolds.
