Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in antimalarial and anticancer agents. Its structure supports the development of kinase inhibitors due to the electron-withdrawing trifluoromethyl group enhancing metabolic stability and binding affinity. Also employed in agrochemicals for creating novel pesticides with improved efficacy and environmental profile. Commonly utilized in research for developing fluorescent probes, leveraging the quinoline core’s photophysical properties.
