Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of antituberculosis agents. It serves as a building block in the preparation of quinoxaline-based compounds that exhibit biological activity, including kinase inhibitors and antimicrobial agents. Its structure allows for functionalization at multiple sites, making it valuable in medicinal chemistry for structure-activity relationship studies. Also employed in the design of organic semiconductors and fluorescent dyes due to the electron-deficient nature of the quinoxaline core.
