Used as an intermediate in pharmaceutical synthesis, particularly in the development of bioactive molecules targeting central nervous system disorders. Its structure allows for selective modification, making it valuable in creating analogs for drug discovery. Commonly employed in the preparation of kinase inhibitors and receptor modulators due to the stability and steric properties provided by the tert-butoxycarbonyl (Boc) protecting group. Also utilized in solid-phase synthesis and combinatorial chemistry for generating compound libraries.
