Used as a key intermediate in peptide synthesis, particularly in the production of modified peptides for pharmaceutical research. It plays a significant role in the development of peptide-based drugs, where the introduction of trifluoromethyl groups can enhance metabolic stability and binding affinity. Commonly employed in solid-phase peptide synthesis (SPPS) to incorporate non-natural amino acids into peptide chains. Its protective Boc group allows for selective deprotection, enabling precise control over peptide assembly. Also utilized in studies exploring the effects of fluorinated amino acids on peptide structure and function, contributing to advancements in medicinal chemistry and drug design.
