Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of isoquinoline-based drugs with potential antitumor, antimicrobial, and anti-inflammatory activities. Its bromo functional group allows for further cross-coupling reactions, enabling the construction of complex molecular structures in medicinal chemistry. Commonly employed in research settings to design kinase inhibitors and central nervous system agents. Also utilized in the preparation of fluorescent probes and organic electronic materials due to its aromatic scaffold.
