Used primarily in peptide synthesis, it serves as a protected form of lysine, ensuring selective reactions during the formation of peptide bonds. The boc group protects the amino group, preventing unwanted side reactions, while the hydrochloride form enhances solubility in various solvents. This compound is crucial in the production of complex peptides and proteins, particularly in pharmaceutical research and development. It is also employed in the study of enzyme mechanisms and protein interactions, aiding in the understanding of biological processes and the design of therapeutic agents.
