Used as a key intermediate in the synthesis of kinase inhibitors, particularly in the development of anticancer agents. Its structure enables selective binding to ATP sites in kinases, making it valuable in targeted therapies. It is also employed in the preparation of pharmaceuticals for treating inflammatory diseases and certain types of leukemia. Due to its heterocyclic framework, it enhances metabolic stability and bioavailability in drug candidates. Commonly utilized in medicinal chemistry research for structure-activity relationship (SAR) studies to optimize potency and selectivity.
