Used in peptide synthesis and pharmaceutical research as a chiral building block. Its primary application lies in the preparation of protected amino alcohol intermediates for the development of bioactive molecules, including antibiotics and enzyme inhibitors. The Boc-protected group allows for selective deprotection under mild acidic conditions, making it valuable in multi-step organic syntheses where functional group compatibility is critical. Also employed in the synthesis of peptidomimetics and other medicinal chemistry scaffolds requiring stereochemical control.
