This compound is primarily used in peptide synthesis as a protected form of lysine, featuring both Z (carbobenzyloxy) protection on the α-amino group and Boc (tert-butoxycarbonyl) protection on the ε-amino group of the side chain. The Boc group safeguards the side chain amino group, preventing unwanted reactions during peptide chain assembly. Its dicyclohexylammonium salt form enhances solubility in organic solvents, making it suitable for solid-phase peptide synthesis (SPPS) and solution-phase methods. It is particularly valuable in creating peptides for pharmaceutical research, where precise control over amino acid sequence is critical. Additionally, it finds utility in the development of bioactive peptides, enzyme inhibitors, and other therapeutic agents. Its stability and compatibility with various coupling reagents make it a reliable choice in synthetic organic chemistry.
