Used in organic synthesis as an intermediate for pharmaceuticals and bioactive compounds. Its structure supports the development of nitrogen-containing heterocyclic systems, which are common in medicinal chemistry. The amine and bromo functional groups allow for further derivatization through cross-coupling reactions, enabling the construction of complex molecules. Applied in research for potential antimicrobial, anticancer, or CNS-active agents due to the isoquinoline core's biological relevance. Also explored in materials science for designing fluorescent probes or ligands in catalysis.
