This chemical is primarily used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS). It serves as a protected amino acid derivative, where the Fmoc (fluorenylmethyloxycarbonyl) group acts as a temporary protecting group for the amino functionality during the synthesis process. The 2-naphthyl side chain provides a hydrophobic and aromatic character to the peptide, which can be beneficial in designing peptides with specific structural or functional properties. It is often employed in the development of bioactive peptides, peptidomimetics, and in research focused on understanding protein-protein interactions. Additionally, its incorporation into peptides can enhance their stability and binding affinity, making it valuable in drug discovery and biochemical studies.
