Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and antiviral agents. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for constructing biologically active molecules. Commonly employed in cross-coupling reactions to introduce the pyrazine core into larger drug-like compounds. Also utilized in agrochemical research for designing novel pesticides due to its ability to enhance metabolic stability and binding affinity in target compounds.
