Used as an intermediate in the synthesis of pharmaceuticals and fine chemicals, particularly in the development of active pharmaceutical ingredients (APIs) where protection of amine functional groups is required. Its hydroxyl group allows for further chemical modifications, enabling the construction of complex molecules. Commonly employed in multi-step organic syntheses due to the stability and selective deprotection characteristics of the tert-butyl carbamate (Boc) protecting group. Suitable in the preparation of beta-amino alcohols and other bioactive structures.
