Used as a key intermediate in the synthesis of kinase inhibitors, particularly in the development of pharmaceuticals targeting cancer and inflammatory diseases. Its structure allows selective binding to ATP sites in kinases, making it valuable in creating targeted therapies. Commonly employed in research for drug discovery due to its ability to modulate signaling pathways involved in cell proliferation and apoptosis. Also utilized in the preparation of analogs for structure-activity relationship (SAR) studies to optimize potency and selectivity in new drug candidates.
