This compound is primarily used in peptide synthesis and pharmaceutical research. It serves as a building block for creating modified peptides, which can be studied for their biological activity or therapeutic potential. The bromine atom at the phenylalanine side chain allows for further chemical modifications, such as cross-coupling reactions, making it valuable in drug discovery and development. Additionally, it is utilized in the study of enzyme-substrate interactions and protein engineering, where specific amino acid modifications are required to understand or alter biological functions. Its role in creating peptide-based drugs or probes for biochemical studies highlights its importance in medicinal chemistry and biotechnology.
