Widely used in peptide synthesis, this compound serves as a protected amino acid building block, particularly in solid-phase peptide synthesis (SPPS). The Fmoc group provides temporary protection to the amino terminus, allowing selective coupling of amino acids in a controlled sequence. Its (S)-configuration ensures stereochemical consistency in the resulting peptides, making it valuable for producing biologically active peptides with high purity. The presence of the oct-7-enoic acid side chain introduces a reactive alkene handle, enabling further modification via thiol-ene chemistry or other alkene-based reactions for conjugation, labeling, or immobilization. This makes the compound especially useful in the development of peptide-based drugs, bioconjugates, and functional biomaterials.
