Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in the preparation of bioactive molecules due to the reactivity of the amine and bromo groups, enabling coupling reactions such as Suzuki or Buchwald-Hartwig aminations. Its pyrimidine core is commonly found in drugs targeting inflammatory diseases and viral infections. Also employed in agrochemical research for designing novel pesticides with improved selectivity.
