Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of antitumor and antimicrobial agents. Its structure supports the development of bioactive molecules due to the presence of the methoxy and isoquinoline moieties, which enhance binding to biological targets. Employed in research for developing kinase inhibitors and central nervous system modulators. Also utilized in the design of fluorescent probes for cellular imaging due to its favorable photophysical properties.
