Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of herbicides and insecticides. Its structure allows for selective functionalization, making it valuable in building complex pyridine-based molecules. Commonly employed in cross-coupling reactions such as Suzuki or Buchwald-Hartwig aminations to introduce aryl or amino groups, enabling the creation of active ingredients in crop protection agents. Also utilized in research for developing novel bioactive compounds due to the electron-withdrawing nature of the nitrile and halogen substituents, which enhance reactivity and binding properties.
