Used as a key intermediate in the synthesis of kinase inhibitors, particularly in the development of anticancer agents. Its structure enables selective binding to protein kinases involved in cell signaling pathways, making it valuable in pharmaceutical research for targeted therapies. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies to optimize potency and selectivity. Also utilized in the preparation of biologically active compounds for treating inflammatory diseases and neurological disorders due to its ability to cross the blood-brain barrier in certain derivatives.
