Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral and anticancer agents. Its structure supports the formation of biologically active quinoxaline derivatives, which are known for their interaction with enzymes and receptors in therapeutic applications. Also employed in research for designing novel heterocyclic compounds with potential antimicrobial properties. Its reactivity allows for functionalization in drug discovery programs and in the preparation of fluorescent dyes for biochemical labeling.
