Used in pharmaceutical research as a key intermediate in the synthesis of biologically active compounds, particularly kinase inhibitors. Shows potential in the development of anticancer agents due to its structural similarity to purine bases, allowing it to interact with enzyme active sites involved in cell signaling pathways. Also explored in the design of antiviral drugs for its ability to mimic nucleosides. Its fused heterocyclic framework enhances binding affinity and selectivity, making it valuable in optimizing drug candidates for improved efficacy and metabolic stability.
