Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and antimicrobial agents. Its functional groups allow for selective modifications, making it valuable in medicinal chemistry for building complex heterocyclic systems. Commonly employed in cross-coupling reactions and nucleophilic substitutions to introduce pyrazine-based scaffolds into bioactive molecules. Also utilized in agrochemical research for designing novel active ingredients with improved efficacy and selectivity.
