This chemical is widely used in peptide synthesis as a protecting group for amino acids, specifically lysine. It helps prevent unwanted side reactions during the formation of peptide bonds. The Boc (tert-butoxycarbonyl) group protects the amino group, while the Ac (acetyl) group protects the side chain of lysine. This dual protection ensures selective reactions at desired sites, making it valuable in the production of complex peptides and proteins. It is particularly useful in solid-phase peptide synthesis, where controlled and stepwise assembly of peptides is required. Additionally, it finds applications in the development of pharmaceuticals, bioactive peptides, and research involving protein engineering.
