Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for creating compounds with high target specificity. Commonly employed in cross-coupling reactions, such as Suzuki or Stille couplings, to introduce aryl or heteroaryl groups. Also utilized in the preparation of agrochemicals and functional materials where halogenated pyridine derivatives enhance reactivity or binding properties.
