Used as an intermediate in the synthesis of agrochemicals, particularly herbicides and insecticides, due to its reactive chlorine groups and heterocyclic structure. Its methyl and chlorine substituents allow for further functionalization, making it valuable in developing active ingredients with enhanced selectivity and stability. Also explored in pharmaceutical research for building bioactive molecules, especially those targeting enzyme inhibition. Its aromatic pyrazine core contributes to electron-deficient character, useful in designing charge-transfer materials for specialty chemicals.
