Used extensively in peptide synthesis as a protected form of lysine. The Boc (tert-butyloxycarbonyl) group safeguards the amino group during the synthesis process, preventing unwanted reactions. After the peptide chain is assembled, the Boc group can be selectively removed under acidic conditions, exposing the amino group for further modifications or coupling reactions. This compound is particularly valuable in solid-phase peptide synthesis (SPPS) and in the production of complex peptides for pharmaceutical research, including the development of therapeutic peptides and peptide-based drugs. Its stability and ease of deprotection make it a preferred choice in organic and medicinal chemistry.
