Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry due to the reactivity of the ketone group and the presence of the chloro and methyl substituents on the pyrazine ring, which allow for further functionalization. Commonly employed in the preparation of biologically active compounds targeting inflammatory diseases and neurological disorders. Also utilized in agrochemical research for the design of novel pesticides with improved selectivity and efficacy.
