Used as an intermediate in the synthesis of protein kinase inhibitors, particularly in the development of anticancer agents. It plays a key role in targeting signaling pathways involved in cell proliferation and survival, making it valuable in pharmaceutical research for treating cancers such as leukemia and solid tumors. Its structure allows selective binding to kinase enzymes, enhancing drug specificity and reducing off-target effects. Commonly utilized in preclinical studies to optimize potency and pharmacokinetic properties of final drug candidates.
