Used in pharmaceutical research as a key intermediate in the synthesis of tyrosine kinase inhibitors, particularly targeting epidermal growth factor receptor (EGFR) pathways. It plays a role in developing anticancer agents, especially for non-small cell lung cancer and other solid tumors. Its structure allows for selective binding and improved pharmacokinetic properties in drug candidates. Also explored in targeted therapy development due to its ability to cross cell membranes and modulate signaling pathways involved in tumor growth and proliferation.
