This compound is primarily used in peptide synthesis as a protected amino acid derivative. It serves as a building block for constructing peptides, where the Boc (tert-butyloxycarbonyl) group protects the amino group, and the 2-Cl-Z (2-chlorobenzyloxycarbonyl) group protects the side chain of lysine. This dual protection allows selective deprotection during peptide chain assembly, ensuring precise control over the synthesis process. It is particularly valuable in producing complex peptides for research, pharmaceuticals, and biotechnology applications, where maintaining the integrity of the lysine residue is critical. Its stability and ease of handling make it a preferred choice in solid-phase peptide synthesis (SPPS) and other peptide-related methodologies.
