Used in pharmaceutical research as a key intermediate in the synthesis of selective kinase inhibitors, particularly in the development of compounds targeting JAK2 and other tyrosine kinases involved in inflammatory diseases and certain cancers. Its structural features support binding to ATP sites in kinases, making it valuable in optimizing potency and selectivity during drug discovery. Also explored in the design of CNS-active agents due to its ability to cross the blood-brain barrier, showing potential in neurodegenerative and psychiatric disorder research.
