Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) that require protected amine functionalities. Its structure allows for selective reactions at specific sites during multi-step syntheses, making it valuable in creating complex drug molecules. Commonly employed in the preparation of central nervous system agents and other bioactive compounds where controlled release or stability of the amine group is essential. Also utilized in research settings for labeling and derivatization of peptides and small molecules.
