Used in pharmaceutical research as a key intermediate in the synthesis of tyrosine kinase inhibitors, particularly those targeting cancer pathways such as EGFR (epidermal growth factor receptor). It plays a role in the development of anticancer agents due to its ability to support structural modifications that enhance binding affinity and selectivity toward specific kinase enzymes. Its derivatives are explored for antitumor activity in various carcinoma cell lines. Also investigated for potential use in targeted therapies for non-small cell lung cancer and other solid tumors.
