Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents and neurodegenerative disease treatments. Its structure supports the creation of bioactive molecules due to the presence of a protected amine group, enabling selective reactions in multi-step organic syntheses. Commonly employed in medicinal chemistry for constructing isoquinoline-based compounds with potential antipsychotic, antidepressant, or anti-Parkinson activity. Also utilized in research settings for designing enzyme inhibitors and receptor ligands.
