Used in peptide synthesis as a building block to introduce the aminoisobutyric acid (Aib) residue, which helps create peptides with unique structural properties. It is particularly valuable in designing peptides with enhanced stability and resistance to enzymatic degradation. The compound is also employed in research to study the effects of Aib on peptide conformation and folding, aiding in the development of novel therapeutic peptides and bioactive molecules. Additionally, it finds application in the preparation of peptidomimetics, which mimic the structure and function of natural peptides for drug discovery and development.
