Used primarily in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS) methods. The Fmoc group serves as a protecting group for the amino acid, allowing for selective deprotection during the synthesis process. Its incorporation into peptides can help in studying peptide structure and function, especially in cases where specific interactions with proteins or receptors are of interest. Additionally, the dichlorophenyl group can enhance the peptide's stability and binding affinity, making it useful in the development of peptide-based drugs or inhibitors. This compound is also employed in research involving peptide modifications to explore biological activity and therapeutic potential.
