Used in pharmaceutical research as an 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. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies to optimize drug potency and selectivity. Also utilized in the preparation of targeted therapies for solid tumors, especially in epidermal growth factor receptor (EGFR) pathway inhibition.
