Used in organic synthesis as an intermediate for pharmaceuticals and bioactive compounds. Shows potential in the development of central nervous system agents due to its structural similarity to known neuroactive molecules. Employed in research settings to study isoquinoline-based receptor ligands, particularly in the context of serotonin and dopamine pathways. Also utilized in the preparation of fluorescent probes for biochemical imaging, leveraging its inherent photophysical properties. Investigated for antimicrobial and anticancer activities in preclinical studies, where derivatives exhibit moderate inhibitory effects against certain cell lines and pathogens.
