This chemical is primarily used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS) methods. It serves as a protected amino acid derivative, where the Fmoc group acts as a protecting group for the amine functionality, allowing for selective deprotection and subsequent peptide chain elongation. The presence of the 2-chlorophenyl group in the structure can impart specific steric and electronic properties to the peptide, which may be useful in designing peptides with targeted biological activity or improved stability. It is commonly employed in the development of pharmaceutical compounds, bioactive peptides, and research tools for studying peptide-protein interactions. Additionally, its chiral nature makes it valuable in the synthesis of enantiomerically pure peptides for applications in drug discovery and development.
