Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of active pharmaceutical ingredients (APIs) that require protected amine functionalities. Its structure allows for selective reactions in multi-step organic syntheses, especially in the development of central nervous system agents and other bioactive molecules. Commonly employed in medicinal chemistry for building complex amine-containing compounds due to the stability and ease of deprotection of the Boc (tert-butoxycarbonyl) group. Also utilized in research settings for the preparation of analogs and derivatives in drug discovery programs.
