Widely used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS) methods. Its Fmoc group serves as a protective group for the amine functionality, allowing for selective deprotection during the synthesis process. The Nalpha-methyl modification enhances the stability of the peptide backbone and can influence the conformational properties of the resulting peptides. The O-benzyl group protects the hydroxyl group of tyrosine, preventing unwanted side reactions. This compound is valuable in the production of modified peptides for research in biochemistry, drug development, and studies of protein-protein interactions. Its applications extend to the synthesis of peptide-based therapeutics and biomaterials.
