Used primarily in peptide synthesis, it serves as a building block for creating structurally complex peptides. Its incorporation into peptide chains enhances the stability and binding affinity of peptides, making it valuable in drug development and biochemical research. Additionally, it is employed in the study of protein-protein interactions and enzyme mechanisms due to its unique aromatic side chain, which can mimic natural amino acids while providing specific structural properties. This makes it useful in designing inhibitors or probes for biological targets.
