Used in pharmaceutical research as a key intermediate in the development of kinase inhibitors, particularly for targeting cancer-related enzymes such as EGFR and VEGFR. Shows potential in the synthesis of compounds with antitumor and antiproliferative activity. Also explored for its role in central nervous system agents due to its ability to cross the blood-brain barrier. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies to optimize drug candidates.
