This compound is primarily used in peptide synthesis as a building block for creating modified peptides. Its bromine substitution on the phenylalanine side chain allows for selective chemical modifications, making it valuable in designing peptide-based drugs or bioactive molecules. It is often employed in research to study enzyme-substrate interactions, receptor binding, or to introduce halogenated motifs into peptides for enhanced stability or activity. Additionally, it serves as a key intermediate in the development of pharmaceuticals targeting specific biological pathways, particularly in cases where halogenation can improve drug efficacy or pharmacokinetics.
