Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of active pharmaceutical ingredients (APIs) targeting central nervous system disorders and metabolic diseases. Its structure allows for selective modification, making it valuable in medicinal chemistry for creating potent and selective drug candidates. Commonly employed in the preparation of kinase inhibitors and receptor modulators due to the stability and bioavailability imparted by the tert-butoxycarbonyl (Boc) protecting group. Also utilized in fragment-based drug discovery for building complex heterocyclic systems.
