Used in peptide synthesis as a building block to introduce D-3-aminobutyric acid into peptide chains. It is particularly valuable in the preparation of modified peptides for research in biochemistry and medicinal chemistry. The Boc group protects the amino functionality during synthesis, allowing for selective deprotection and further coupling reactions. This compound is also employed in the development of peptide-based drugs and bioactive molecules, where the D-configuration of the amino acid can influence biological activity and stability. Additionally, it finds application in the study of enzyme-substrate interactions and the design of enzyme inhibitors.
