Used in peptide synthesis, particularly for solid-phase peptide synthesis (SPPS), where it serves as a building block for incorporating modified amino acids into peptide chains. The Fmoc group provides protection for the alpha-amino group, while the octanoyl group introduces a hydrophobic side chain, enabling the study of lipidated peptides or peptides with enhanced membrane interaction properties. It is valuable in research focused on peptide-based drug development, biomaterials, and studies of protein-protein interactions. The compound’s structure allows for the creation of peptides with tailored properties, such as improved stability or specific binding capabilities.
