Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic acetylcholine receptor modulators. It plays a role in creating compounds targeting neurological disorders such as depression, anxiety, and cognitive dysfunction. Its trifluoromethyl group enhances metabolic stability and bioavailability, making it valuable in medicinal chemistry for optimizing drug candidates. Also employed in agrochemicals for improving the efficacy of certain pesticides due to its electron-withdrawing properties and resistance to degradation.
