Used in pharmaceutical research as a key intermediate in the synthesis of selective kinase inhibitors, particularly in the development of compounds targeting inflammatory diseases and certain cancers. Its structural features enable strong binding to specific enzyme active sites, enhancing therapeutic potency. Also explored in the design of central nervous system agents due to its ability to cross the blood-brain barrier. Commonly employed in structure-activity relationship (SAR) studies to optimize drug candidates for improved metabolic stability and bioavailability.
