Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) for central nervous system (CNS) drugs and kinase inhibitors. Its structure allows for selective modification, making it valuable in medicinal chemistry for building complex molecules with high specificity. Commonly employed in the preparation of protease inhibitors and receptor agonists/antagonists due to the protected amine group that enables stepwise synthesis. Also utilized in the production of drug candidates for oncology and neurodegenerative diseases.
