Used in pharmaceutical research as a key intermediate in the synthesis of biologically active compounds, particularly kinase inhibitors. Shows potential in the development of anti-inflammatory and anticancer agents due to its structural similarity to purine bases, allowing it to interact with cellular enzymes and receptors. Also employed in the design of selective probes for studying enzyme function in cellular pathways. Its derivatives are explored for CNS-related drug discovery owing to their ability to cross the blood-brain barrier.
