Used in peptide synthesis as a protecting group for proline residues, ensuring selective reactions during the formation of peptide bonds. It is particularly valuable in the production of complex peptides and pharmaceuticals, where precise control over amino acid reactivity is required. The Boc group can be easily removed under mild acidic conditions, making it a versatile tool in organic and medicinal chemistry. Additionally, it aids in the synthesis of bioactive compounds and drug intermediates, contributing to the development of therapeutic agents.
