Used as a key intermediate in the synthesis of kinase inhibitors, particularly in pharmaceuticals targeting cancer. It shows significant application in developing drugs that modulate protein kinases involved in cell signaling pathways. Its structure allows selective binding to ATP sites in kinases, making it valuable in creating targeted therapies for oncology. Also employed in research for inflammatory diseases and neurodegenerative disorders due to its ability to cross the blood-brain barrier and modulate central nervous system activity.
