Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its structure supports binding to enzyme active sites, enhancing selectivity and potency. Also employed in agrochemicals to improve metabolic stability and bioavailability. Commonly utilized in research for designing novel bioactive molecules due to the electron-withdrawing trifluoromethyl group and aromatic quinoline core, which contribute to favorable pharmacokinetic properties.
