Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of agrochemicals and bioactive molecules. Its structure allows for the introduction of trifluoromethylbenzyl groups, which can enhance metabolic stability and lipophilicity in drug candidates. Commonly employed in medicinal chemistry for constructing nitrogen-containing heterocycles and as a building block in the preparation of potent enzyme inhibitors. Also utilized in research settings for labeling and derivatization of carbonyl compounds due to its reactivity with aldehydes and ketones.
