Used in peptide synthesis as a protecting group for amino acids, ensuring selective reactions during the formation of peptide bonds. It is particularly valuable in creating complex peptides with specific structural properties, such as helical conformations, due to its ability to introduce steric hindrance. This makes it a key component in the development of bioactive peptides, pharmaceuticals, and research tools for studying protein folding and stability. Additionally, it is employed in the production of peptidomimetics, which mimic natural peptides for therapeutic applications.
