Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and anticancer agents. Its structure supports the creation of complex heterocyclic systems found in bioactive molecules. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to the presence of halogen and heteroaromatic functionalities. Also utilized in cross-coupling reactions such as Suzuki or Buchwald-Hartwig to build more complex quinoline derivatives with potential biological activity.
