Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) agents and neuroactive compounds. Its structure supports the construction of complex isoquinoline-based molecules, which are found in certain analgesics, antipsychotics, and anti-Parkinson’s drugs. The tert-butyloxycarbonyl (Boc) protecting group allows for selective amine reactivity, making it valuable in multi-step organic syntheses, especially in peptide coupling and heterocyclic chemistry. Commonly employed in research settings for medicinal chemistry campaigns targeting neurological disorders.
