Used as a key intermediate in the synthesis of agrochemicals, particularly herbicides and insecticides, due to its reactive chlorine at position 2 and electron-deficient pyrimidine ring. Its trifluoroethoxy group at position 4 enhances lipophilicity and metabolic stability, making it valuable in the development of active ingredients with improved environmental persistence and target specificity. Also employed in medicinal chemistry for constructing fluorinated heterocyclic compounds with potential biological activity.
