This compound is primarily used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS). It serves as a protected amino acid derivative, where the Fmoc (fluorenylmethyloxycarbonyl) group protects the amine functionality, and the Pbf (2,2,4,6,7-pentamethyldihydrobenzofuran-5-sulfonyl) group protects the guanidine side chain of norarginine. This protection is crucial to prevent unwanted side reactions during the peptide assembly process. It is widely employed in the production of peptides for research, pharmaceuticals, and biotechnology applications, enabling the precise construction of peptide chains with specific sequences. Its stability and compatibility with SPPS make it a valuable tool for synthesizing complex peptides and proteins.
