Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of beta-amino alcohols and chiral building blocks for drug development. Commonly employed in the preparation of protease inhibitors and other biologically active molecules due to its ability to act as a protected amino alcohol derivative. Its tert-butyloxycarbonyl (Boc) group allows for selective deprotection under mild acidic conditions, making it valuable in multi-step organic syntheses, especially in peptide and peptidomimetic chemistry.
