Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules targeting neurological and inflammatory disorders. Its structure supports the design of potent, selective drug candidates due to the bromine handle for further functionalization via cross-coupling reactions. Commonly employed in medicinal chemistry research for building complex heterocyclic systems found in CNS-active agents. Also utilized in the preparation of fluorescent probes for biochemical assays, leveraging its quinolinone core for optical properties.
