Used as an intermediate in the synthesis of peptides, particularly in the preparation of lysine-containing compounds. It is valuable in pharmaceutical research for developing drugs and bioactive molecules. The Boc group provides protection for the amino group during peptide coupling reactions, ensuring selective chemical transformations. Additionally, it is employed in the production of modified amino acids for studying protein structure and function. Its stability and ease of deprotection make it a preferred choice in organic and medicinal chemistry applications.
