This chemical is widely used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS) methods. It serves as a protected amino acid derivative, where the Fmoc (fluorenylmethyloxycarbonyl) group protects the amino group, and the Boc (tert-butyloxycarbonyl) groups protect the guanidine side chain of homoarginine. This protection scheme is crucial for the stepwise assembly of peptides, allowing selective deprotection and coupling reactions. It is especially valuable in synthesizing peptides containing homoarginine, a non-natural amino acid often used in biochemical and pharmacological research to study enzyme-substrate interactions, peptide stability, and protein folding. Its application extends to the development of peptide-based drugs, vaccines, and diagnostic tools, where precise control over peptide structure is essential.
