Used as a key intermediate in the synthesis of tyrosine kinase inhibitors, particularly in the development of anticancer agents. Its structure supports binding to enzyme active sites involved in signal transduction pathways, making it valuable in pharmaceutical research for targeting tumor growth and proliferation. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies to optimize potency and selectivity of drug candidates. Also utilized in the preparation of small molecule inhibitors targeting receptor tyrosine kinases such as EGFR and VEGFR.
