This chemical is primarily utilized in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS) methods. It serves as a protected amino acid derivative, where the Fmoc group ensures temporary protection of the amine functionality during the synthesis process. The tert-butyl (tBu) group protects the hydroxyl side chain of serine, while the PSiMe,MePro group provides additional stability and protection for the serine residue. This compound is especially valuable in constructing complex peptides with multiple serine residues, as it allows for selective deprotection and coupling steps. Its application is critical in producing peptides for pharmaceutical research, drug development, and biochemical studies, where precise control over peptide structure is essential.
