Used in peptide synthesis as a protecting group for homoserine, ensuring selective reactions during the formation of peptide bonds. It is particularly valuable in solid-phase peptide synthesis (SPPS) to prevent unwanted side reactions. The Boc group can be easily removed under acidic conditions, allowing for further modifications or elongation of the peptide chain. It is also employed in the preparation of complex peptides and proteins for research in biochemistry and drug development. Additionally, it serves as a key intermediate in the synthesis of bioactive compounds and pharmaceutical agents.
