Used in pharmaceutical research as a building block for synthesizing biologically active compounds, particularly in the development of kinase inhibitors and other medicinal agents targeting cancer and inflammatory diseases. Its structure mimics purine bases, allowing integration into molecules that interact with enzymes and receptors in cellular signaling pathways. Also employed in agrochemical research for designing novel pesticides and herbicides due to its stability and reactivity in heterocyclic synthesis. Commonly utilized in cross-coupling reactions to construct complex nitrogen-containing scaffolds in drug discovery.
