This chemical is widely used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS). It serves as a building block for introducing brominated phenylalanine residues into peptide chains, which can be crucial for studying protein structure and function. The Fmoc group provides protection for the amino group during synthesis, ensuring selective reactions. The bromine atom on the phenyl ring can be utilized for further functionalization or as a handle for bioconjugation, making it valuable in drug development and biochemical research. Additionally, it is employed in the preparation of peptide-based materials and in the study of enzyme-substrate interactions.
