Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its structure allows for selective binding to enzyme targets involved in cell signaling pathways. Commonly utilized in research for designing drugs that target tyrosine kinases, which play roles in tumor growth and inflammation. Also employed in the preparation of antiviral agents due to its ability to mimic purine nucleotides. Its derivatives are explored in medicinal chemistry for improved bioavailability and target specificity.
