Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in cross-coupling reactions such as Suzuki-Miyaura and Heck reactions. Its iodo functionality provides high reactivity in palladium-catalyzed transformations, making it valuable for constructing carbon-carbon bonds. The presence of both methyl and trifluoromethyl groups allows for electronic and steric tuning in target molecules, enhancing its utility in drug discovery and development of bioactive compounds.
