Used extensively in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS) methods. It serves as a building block for introducing the homocyclohexylalanine moiety into peptides, which can enhance the stability and conformational rigidity of the peptide structure. This makes it valuable in the development of peptide-based drugs, where specific structural features are required for biological activity. Additionally, it is employed in research to study peptide-protein interactions and to design peptides with improved pharmacokinetic properties. Its Fmoc protection group allows for easy deprotection under mild conditions, making it compatible with automated peptide synthesizers.
