Used as an intermediate in the synthesis of pharmaceutical compounds, particularly kinase inhibitors. Its structure supports the development of targeted therapies in oncology, where it helps modulate signaling pathways involved in cancer cell proliferation. The compound's halogenated quinazoline core enhances binding affinity to specific enzyme targets, making it valuable in drug discovery efforts for treating solid tumors. It is also employed in medicinal chemistry research to optimize potency and selectivity of new drug candidates.
