Used in peptide synthesis as a protecting group for glutamic acid, ensuring selective reactions during the formation of peptide bonds. It is particularly valuable in solid-phase peptide synthesis (SPPS) for creating complex peptides and proteins. The Boc group can be easily removed under acidic conditions without affecting other functional groups, making it a versatile tool in organic and medicinal chemistry. It is also employed in the development of pharmaceutical compounds, where precise control over amino acid reactivity is crucial. Additionally, it aids in the study of peptide structure and function, contributing to advancements in biochemistry and drug discovery.
