Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) that target central nervous system disorders. Its structure supports the creation of compounds with receptor modulating activity, especially in serotonin and dopamine pathways. Commonly utilized in medicinal chemistry for constructing drug candidates due to the protected amine group, which allows selective reactions during multi-step syntheses. Also employed in the preparation of protease inhibitors and receptor antagonists. Its hydrochloride salt form enhances stability and solubility, making it suitable for laboratory-scale reactions and process development in drug discovery.
