Used as a key intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the development of herbicides and fungicides due to its reactive alkyne and electron-withdrawing trifluoromethyl groups. The compound's structure allows for further functionalization via click chemistry, making it valuable in medicinal chemistry for building complex molecules. It is also employed in the preparation of specialty polymers and fluorescent dyes, where the trifluoromethyl aniline moiety enhances stability and lipophilicity.
