Used in pharmaceutical research as a key intermediate in the synthesis of biologically active compounds, particularly kinase inhibitors. Serves as a building block in the development of potential anticancer agents due to its structural similarity to purine bases, allowing it to interact with enzyme active sites. Also employed in the preparation of fluorescent probes and optoelectronic materials owing to its nitrogen-rich heterocyclic framework. Its bromine substituents enable further functionalization via cross-coupling reactions, making it valuable in medicinal chemistry and materials science.
