Used as a key intermediate in the synthesis of kinase inhibitors, particularly in pharmaceutical research targeting cancer therapies. It serves as a building block for compounds that modulate protein kinases involved in cell signaling, proliferation, and apoptosis. Its structure allows for selective binding and optimization in drug design, especially in developing treatments for solid tumors and hematological malignancies. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies to enhance potency and selectivity of candidate drugs.
