This chemical is primarily used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS). It serves as a dual-protected amino acid derivative, where the Boc (tert-butoxycarbonyl) and Fmoc (fluorenylmethyloxycarbonyl) groups protect the amine functionalities. This allows for selective deprotection and sequential addition of amino acids during peptide chain assembly. Its application is crucial in the synthesis of complex peptides and proteins, enabling precise control over the structure and functionality of the final product. It is also employed in the development of peptide-based drugs, biomaterials, and research tools in biochemistry and molecular biology.
