Used as a key intermediate in the synthesis of biologically active quinazoline derivatives, particularly in pharmaceutical research targeting kinase inhibitors. It serves in the development of anticancer agents due to its ability to modify the quinazoline core, enhancing binding affinity to enzyme active sites. Also employed in medicinal chemistry for structure-activity relationship (SAR) studies, helping optimize potency and selectivity of drug candidates. Its bromine substituents allow further functionalization via cross-coupling reactions, enabling rapid diversification in compound libraries for high-throughput screening.
