Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active compounds. Its pyrazine core with chlorine and tert-butyl ester substituents allows for selective functionalization, making it valuable in medicinal chemistry for building complex heterocyclic systems. Commonly employed in research settings to design drug candidates targeting inflammatory diseases, cancer, and central nervous system disorders. Also utilized in agrochemical research for developing novel pesticides due to its stability and reactivity profile.
