Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry due to its reactive functional groups, enabling coupling reactions to form more complex heterocyclic systems. Also employed in agrochemical research for designing novel pesticides with improved efficacy and selectivity. Its chloropyrazine core contributes to electron-deficient aromatic systems useful in cross-coupling reactions for drug discovery.
