Used in solid-phase peptide synthesis, particularly for incorporating sterically hindered, non-natural amino acids into peptide chains. The compound’s alpha-methyl group provides enhanced metabolic stability to the resulting peptide by preventing degradation at that site. The FMOC and BOC protecting groups allow for selective deprotection and stepwise assembly, making it valuable in synthesizing complex peptides for pharmaceutical research, especially in developing peptide-based drugs with improved bioavailability and resistance to enzymatic breakdown. Commonly applied in the production of therapeutic peptides, enzyme inhibitors, and probes for biochemical studies.
