Used primarily as a building block in organic synthesis, especially in pharmaceuticals and agrochemicals. Its alkyne functionality allows participation in coupling reactions such as Sonogashira and click chemistry, enabling the construction of complex molecules. The electron-withdrawing trifluoromethyl group enhances stability and influences reactivity, making it valuable in the development of bioactive compounds. It is also employed in materials science for designing fluorinated organic semiconductors and specialty polymers with improved thermal and oxidative stability.
