Used as a key intermediate in the synthesis of pharmaceuticals, particularly in antimalarial and anticancer agents. Its structure supports the development of kinase inhibitors due to the electron-withdrawing trifluoromethyl group enhancing binding affinity. Also employed in agrochemicals for crop protection, where it contributes to improved metabolic stability and lipophilicity. Additionally, it serves as a building block in materials science for fluorescent probes, leveraging the quinoline core’s photophysical properties.
