Used as a key intermediate in the synthesis of agrochemicals, particularly herbicides and insecticides, due to its reactive halogen groups and electron-withdrawing sulfonyl moiety. Its structure allows for easy functionalization, making it valuable in creating active ingredients that target specific plant or pest metabolic pathways. Also employed in pharmaceutical research for developing bioactive molecules, where the pyridine core contributes to binding affinity and stability. Commonly utilized in cross-coupling reactions such as Suzuki or Buchwald-Hartwig to build complex molecules in crop protection agents and medicinal chemistry.
