Used primarily in peptide synthesis, it serves as a building block for creating peptides with specific sequences. The Fmoc group provides protection for the amino group during the synthesis process, ensuring selective reactions at other sites. It is particularly valuable in solid-phase peptide synthesis (SPPS), where it helps in the stepwise assembly of peptides. Its application extends to the development of pharmaceuticals, bioactive peptides, and research tools in biochemistry and molecular biology. The compound is also employed in the study of protein-protein interactions and the design of peptide-based drugs.
