Used as a key intermediate in the synthesis of selective kinase inhibitors, particularly in the development of anticancer agents. Its structure allows for specific binding to ATP pockets in protein kinases, making it valuable in drug discovery programs targeting tumor growth and proliferation. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its modifiable functional groups. Also utilized in the preparation of small-molecule therapeutics aimed at treating inflammatory diseases and certain types of leukemia.
