Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) agents and antipsychotic drugs. Its structure supports binding to neurological receptors, making it valuable in medicinal chemistry for designing dopamine and serotonin modulators. Also employed in research for novel isoquinoline-based compounds with potential anticancer and antimicrobial activity. Its methoxy and amine functional groups allow for easy modification in multi-step organic syntheses.
