Used in pharmaceutical research as an intermediate in the synthesis of biologically active compounds, particularly in the development of kinase inhibitors. It serves as a building block for novel drug candidates targeting cancer and inflammatory diseases. Its bromine functionality allows for further modification via cross-coupling reactions, making it valuable in medicinal chemistry for structure-activity relationship studies. Also employed in the preparation of fluorescent probes and materials for optoelectronic applications due to its nitrogen-rich heterocyclic framework.
