Used as a key intermediate in the synthesis of biologically active quinoxaline derivatives, particularly in pharmaceuticals targeting kinase inhibition. It serves in the development of anticancer agents due to its ability to modify core structures that interact with enzyme targets involved in cell proliferation. Also employed in medicinal chemistry research for constructing libraries of heterocyclic compounds to screen for antimicrobial and anti-inflammatory activity. Its bromo functional group allows for further cross-coupling reactions, making it valuable in structure-activity relationship (SAR) studies.
