Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure supports the formation of heterocyclic frameworks common in medicinal chemistry. It is also employed in research settings for the preparation of fluorescent dyes and optoelectronic materials due to its conjugated system and ability to undergo functionalization. Commonly utilized in combinatorial chemistry and drug discovery for building complex quinoxaline-based scaffolds with potential anti-inflammatory, antiviral, or anticancer activity.
