Used as a key intermediate in the synthesis of cyclin-dependent kinase (CDK) inhibitors, particularly in the development of anticancer agents. Its structure allows selective binding to CDK2 and CDK4 enzymes, making it valuable in targeting tumor cell proliferation. Commonly employed in medicinal chemistry for optimizing kinase inhibitor candidates in drug discovery programs. Also utilized in structure-activity relationship (SAR) studies to enhance potency and selectivity of CDK-targeted therapeutics.
