Used primarily as a key intermediate in the synthesis of pharmaceuticals and agrochemicals. Its strong electron-withdrawing trifluoromethyl groups enhance reactivity in coupling reactions, making it valuable in the preparation of sulfonamides, which are common motifs in bioactive molecules. Frequently employed in the development of protease inhibitors and other therapeutic agents due to its ability to improve metabolic stability and binding affinity. Also utilized in materials science for modifying polymer properties and in the creation of specialty chemicals requiring high chemical resistance and thermal stability.
