Used as an 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 pyridine-based compounds. Commonly employed in cross-coupling reactions such as Suzuki or Heck reactions to build biaryl systems found in bioactive molecules. Also utilized in the preparation of kinase inhibitors and other medicinal agents targeting specific enzymes. Its halogen atoms enable stepwise substitution, offering flexibility in synthetic routes for drug discovery and process chemistry.
