Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of agrochemicals and active pharmaceutical ingredients (APIs). Its halogen substituents allow for selective cross-coupling reactions, making it valuable in building complex molecules through palladium-catalyzed reactions like Suzuki or Buchwald-Hartwig aminations. Commonly employed in the creation of herbicides, insecticides, and kinase inhibitors due to its ability to enhance metabolic stability and binding affinity in target compounds.
