This chemical is primarily used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS). It serves as a protected amino acid derivative, where the Boc (tert-butoxycarbonyl) group protects the amine functionality, and the Fmoc (fluorenylmethyloxycarbonyl) group protects the side chain amine of the phenylalanine residue. This dual protection allows for selective deprotection and coupling in the stepwise construction of peptides. It is especially useful in the synthesis of complex peptides where precise control over the sequence and protection of functional groups is required. The compound is also employed in the preparation of peptide-based pharmaceuticals, where the incorporation of modified amino acids can enhance the stability, activity, or specificity of the final product.
