Used as a key intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the development of herbicides and fungicides. Its structure allows for selective substitution reactions, making it valuable in creating active ingredients that target specific plant or fungal enzymes. Also employed in research for novel kinase inhibitors due to the reactivity of the halogenated pyridine ring. Commonly utilized in cross-coupling reactions such as Suzuki or Buchwald-Hartwig aminations to build complex molecules in drug discovery.
