Used as a key intermediate in the synthesis of agrochemicals, particularly herbicides and insecticides, due to its reactive halogen and electron-deficient pyrimidine ring. Its structure allows for easy functionalization, making it valuable in creating active ingredients that target specific plant or pest biological pathways. Also employed in medicinal chemistry for developing pharmaceuticals, where the trifluoromethyl and chloro groups enhance metabolic stability and binding affinity. Commonly utilized in cross-coupling reactions such as Suzuki or Buchwald-Hartwig to build complex molecules in crop protection and drug discovery research.
