This compound is widely used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS). It serves as a protected amino acid derivative, where the Fmoc group protects the amino group, and the Boc group protects the side chain of ornithine. This allows for selective deprotection and coupling during the stepwise assembly of peptides. Its application is crucial in the production of complex peptides and proteins for research, pharmaceuticals, and biotechnology. Additionally, it is employed in the development of peptide-based drugs, vaccines, and diagnostic tools due to its stability and compatibility with automated peptide synthesizers.
