Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry due to its reactive halogen groups, which allow for further functionalization through cross-coupling reactions. Commonly employed in the preparation of bioactive quinoxaline derivatives with potential antitumor, antibacterial, and anti-inflammatory properties. Also utilized in research settings for the design of novel heterocyclic compounds in drug discovery programs.
