Used as a key intermediate in the synthesis of epidermal growth factor receptor (EGFR) inhibitors, particularly in targeted cancer therapies. Its structure enables selective modification to develop tyrosine kinase inhibitors, which are important in treating non-small cell lung cancer and other solid tumors. The compound’s reactivity supports coupling reactions and derivatization to enhance drug potency and bioavailability. It is primarily utilized in pharmaceutical research and development for designing novel anticancer agents.
