Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of agrochemicals and active ingredients in crop protection products. Its structure allows for selective functionalization, making it valuable in creating herbicides and insecticides. Also employed in medicinal chemistry for constructing kinase inhibitors and other biologically active molecules due to the presence of reactive bromine and electron-withdrawing trifluoromethyl group. Commonly used in cross-coupling reactions such as Suzuki and Negishi couplings to form carbon-carbon bonds in complex molecule assembly.
