This chemical is primarily used in peptide synthesis as a protected amino acid derivative. The Boc (tert-butyloxycarbonyl) group serves as a temporary protecting group for the amine functionality, preventing unwanted reactions during the synthesis process. The Phe(4-NHZ) moiety, with a 4-nitrobenzyl ester group, offers additional protection for the carboxyl group, ensuring selective deprotection and coupling steps. The DCHA (dicyclohexylamine) salt form enhances the stability and solubility of the compound, making it easier to handle and store. It is particularly valuable in the production of complex peptides, where precise control over the sequence and protection of amino acids is critical. Its application is common in pharmaceutical research and development, especially in the creation of peptide-based drugs and bioactive compounds.
