Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other bioactive molecules. Its functional groups allow for selective cross-coupling reactions, making it valuable in medicinal chemistry for constructing complex heterocyclic systems. Commonly employed in research settings to introduce the pyrazine scaffold into target compounds with potential antitumor, antiviral, or anti-inflammatory activity. Also utilized in agrochemical research for designing novel pesticides and herbicides due to its reactivity and structural features.
