Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs). It plays a key role in the preparation of piperidine derivatives, which are commonly found in drugs targeting the central nervous system. Also utilized in peptide chemistry for protecting amine groups during complex organic reactions. Its tert-butoxycarbonyl (Boc) group provides stability and ease of removal, making it valuable in multi-step synthetic processes. Additionally, it is employed in research and development for creating novel compounds with potential therapeutic applications.
