Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly targeting tyrosine kinases involved in cancer cell proliferation. Its structure supports binding to enzyme active sites, making it valuable in developing anticancer agents. Also employed in the design of targeted protein degraders like PROTACs, where it acts as a warhead component to induce degradation of disease-causing proteins. Commonly utilized in structure-activity relationship (SAR) studies to optimize potency and selectivity in drug candidates.
