Used as a key intermediate in the synthesis of bioactive molecules, particularly in pharmaceuticals targeting central nervous system disorders. It serves as a building block for isoquinoline-based compounds with potential anticonvulsant, antidepressant, and antitumor activities. Its bromo functionality allows for further functionalization via cross-coupling reactions, making it valuable in medicinal chemistry for developing novel drug candidates. Also employed in the preparation of fluorescent probes and heterocyclic materials due to its stable aromatic core and derivatization potential.
