Used in peptide synthesis as a protected amino acid derivative, it helps in the controlled addition of lysine residues to peptide chains. The Boc group provides temporary protection for the amino group, while the Ipr group safeguards the side chain, ensuring selective reactions during synthesis. This compound is particularly valuable in producing complex peptides for pharmaceutical research and drug development, where precise sequence assembly is critical. It is also employed in the study of protein structure and function, aiding in the creation of modified peptides for biochemical investigations.
