Used as a key intermediate in the synthesis of kinase inhibitors, particularly in pharmaceutical research targeting cancer therapies. Its structure allows for selective modification, making it valuable in developing compounds that inhibit protein kinases involved in tumor growth and inflammation. Commonly utilized in medicinal chemistry for constructing pyrazolopyrimidine-based drug candidates, especially in the development of tyrosine kinase and cyclin-dependent kinase inhibitors. Also employed in research settings to explore structure-activity relationships in heterocyclic compounds with potential antiviral or antiproliferative activity.
