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 the amino group after deprotection, making it valuable in multi-step organic syntheses. Commonly employed in the preparation of kinase inhibitors and other bioactive molecules where controlled coupling reactions are needed. Also utilized in the production of specialty chemicals and research compounds due to its stability and compatibility with various reaction conditions.
