Used in pharmaceutical research as a key intermediate in the synthesis of biologically active compounds, particularly kinase inhibitors. It serves as a building block in the development of potential anticancer and antiviral agents due to its ability to modulate enzyme activity. Its bromo functional group allows for further derivatization via cross-coupling reactions, making it valuable in medicinal chemistry for structure-activity relationship studies. Also employed in the preparation of fluorescent probes and optoelectronic materials owing to its heterocyclic scaffold with favorable electronic properties.
