Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of active pharmaceutical ingredients (APIs) where protection of amine functionalities is required. Its structure allows for selective reactions in multi-step organic syntheses, especially in the preparation of beta-amino alcohols and heterocyclic compounds. Commonly employed in medicinal chemistry for constructing protease inhibitors and receptor agonists. Also utilized in the production of agrochemicals and specialty polymers due to its stability and reactivity profile in coupling reactions.
