Used as a key intermediate in the synthesis of kinase inhibitors, particularly in the development of anticancer agents. Its structure allows for selective binding to ATP sites in protein kinases, making it valuable in pharmaceutical research for targeting signaling pathways involved in tumor growth. Commonly employed in the preparation of compounds with activity against leukemia and solid tumors. Also utilized in medicinal chemistry for structure-activity relationship (SAR) studies to optimize potency and selectivity of drug candidates.
