Used in pharmaceutical research as a key intermediate in the development of kinase inhibitors, particularly for targeting enzymes involved in inflammatory diseases and certain cancers. Its structure supports binding to ATP sites in kinases, making it valuable in optimizing selectivity and potency of drug candidates. Also explored in the design of CNS-active agents due to its ability to cross the blood-brain barrier. Employed in structure-activity relationship (SAR) studies to enhance metabolic stability and reduce off-target effects in lead compounds.
