Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly for targeting cancer-related enzymes such as cyclin-dependent kinases (CDKs). Its structure supports binding to ATP sites in kinases, making it valuable in developing anti-tumor agents. Also employed in structure-activity relationship (SAR) studies to optimize potency and selectivity in drug candidates. Commonly utilized in preclinical studies to evaluate anticancer activity and pharmacokinetic properties.
