Used in pharmaceutical research as a key intermediate in the synthesis of selective kinase inhibitors, particularly those targeting tyrosine kinases involved in cancer cell proliferation. It plays a role in developing compounds with potential activity against tumors by modulating signaling pathways. Its structure supports binding affinity and selectivity, making it valuable in optimizing drug candidates for improved efficacy and reduced side effects. Also explored in the design of central nervous system agents due to its ability to cross the blood-brain barrier.
