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 acts as a temporary protecting group for the amino group of ornithine. This allows for selective deprotection during the synthesis process, enabling the stepwise construction of peptides. It is especially valuable in the production of complex peptides and proteins for research, pharmaceuticals, and biotechnology applications. Its stability and compatibility with SPPS make it a key reagent in the development of therapeutic peptides, vaccines, and other biologically active compounds.
