Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly for anticancer agents. Its structure allows for selective modification, making it valuable in developing compounds that target specific signaling pathways in tumor cells. Also employed in the preparation of fluorescent probes due to its electron-deficient aromatic system, useful in bioimaging and molecular sensing applications. Commonly utilized in medicinal chemistry for structure-activity relationship (SAR) studies within quinoxaline-based drug candidates.
