Used as a protected intermediate in organic synthesis, particularly in the preparation of beta-amino alcohols. The compound serves as a building block in pharmaceutical synthesis where the tert-butyl carbamate group acts as a protecting group for the amine functionality, allowing selective reactions at other sites. Its diol structure enables further functionalization through esterification or ether formation. Commonly employed in the development of protease inhibitors and other bioactive molecules where controlled deprotection and coupling steps are required. Also utilized in the synthesis of chiral auxiliaries and ligands for asymmetric catalysis.
