Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral and antibacterial agents. Its structure supports the formation of biologically active quinoxaline derivatives, which are explored for their potential in drug discovery. Also employed in the preparation of fluorescent dyes and sensors due to its ability to participate in conjugated systems, enhancing optical properties. Additionally, it finds use in research settings for designing kinase inhibitors and other targeted therapies in oncology.
