Used in pharmaceutical research as a key intermediate in the synthesis of tyrosine kinase inhibitors, particularly those targeting epidermal growth factor receptor (EGFR). It plays a role in the development of anticancer agents due to its ability to interfere with signaling pathways involved in tumor growth and proliferation. Its structure supports high selectivity and binding affinity to kinase enzymes, making it valuable in optimizing drug candidates for improved efficacy and reduced side effects. Also investigated for use in targeted therapies for non-small cell lung cancer and other solid tumors.
