This chemical is primarily used in peptide synthesis as a protected amino acid derivative. It serves as a building block for constructing peptides, particularly in solid-phase peptide synthesis (SPPS) methodologies. The Boc (tert-butyloxycarbonyl) group protects the amino group during synthesis, while the 2,4-dichloro modification on the phenylalanine side chain can influence peptide interactions and stability. It is especially useful in research and development of biologically active peptides, including those with potential therapeutic applications. Its application is critical in the study of peptide structure-activity relationships and in the development of peptide-based drugs.
