Used as a key intermediate in the synthesis of agrochemicals, particularly herbicides and insecticides, due to its reactive halogen groups that allow for further functionalization. Its electron-deficient pyrimidine ring facilitates nucleophilic aromatic substitution, making it valuable in building active ingredients for crop protection products. Also employed in pharmaceutical research for developing novel compounds with biological activity, especially in kinase inhibitor scaffolds. Commonly utilized in cross-coupling reactions such as Suzuki or Buchwald-Hartwig to form carbon-carbon or carbon-nitrogen bonds in advanced synthetic pathways.
