Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. It is valued for its ability to enhance metabolic stability and binding affinity in drug molecules due to the electron-withdrawing trifluoromethyl group. Commonly found in compounds targeting inflammatory diseases and certain viral infections. Also employed in agrochemicals for improving the efficacy of crop protection agents. Its rigid heterocyclic structure supports the design of high-affinity ligands in medicinal chemistry.
