Used in the synthesis of peptides and peptidomimetics, particularly in the development of pharmaceuticals. It serves as a key intermediate in creating compounds with potential therapeutic effects, especially in targeting diseases where modulation of protein-protein interactions is crucial. The trifluoromethyl group enhances the metabolic stability and bioavailability of the resulting molecules, making it valuable in drug discovery. It is also employed in research to study enzyme inhibition and receptor binding, aiding in the design of more effective and selective drugs.
