Used primarily in pharmaceutical research as an intermediate in the synthesis of biologically active compounds, particularly kinase inhibitors. It serves as a scaffold in the development of potential anticancer agents due to its ability to interact with specific enzyme targets involved in cell signaling pathways. Its structure allows for selective binding to ATP sites in kinases, making it valuable in designing drugs for targeted cancer therapies. Also investigated for use in central nervous system agents due to its ability to cross the blood-brain barrier.
