Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of agrochemicals and active pharmaceutical ingredients (APIs). Its structure allows for selective functionalization, making it valuable in creating complex organic molecules. Commonly employed in cross-coupling reactions such as Suzuki or Heck reactions to build carbon-carbon bonds. Also utilized in the production of herbicides and plant growth regulators due to its pyridine backbone, which is prevalent in many bioactive compounds.
