Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) where pyrrolidine scaffolds are present. Its protected amine group allows for selective reactions in multi-step organic syntheses, making it valuable in medicinal chemistry. Commonly employed in the preparation of protease inhibitors, receptor agonists, and kinase inhibitors. Also utilized in the production of fine chemicals and research compounds requiring chiral building blocks with nitrogen-containing heterocycles.
