Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and antiviral agents. Its halogenated quinoline structure enables selective functionalization, making it valuable in medicinal chemistry for constructing bioactive molecules. Commonly employed in cross-coupling reactions such as Suzuki or Buchwald-Hartwig to introduce aryl or amino groups, it supports the creation of complex drug candidates. Also explored in agrochemical research for designing novel active ingredients with improved stability and target specificity.
