Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic receptor modulators and other central nervous system agents. Commonly employed in the preparation of active pharmaceutical ingredients (APIs) for drugs targeting neurological disorders. Also utilized in agrochemical research for the development of novel pesticides due to its ability to enhance bioactivity in certain heterocyclic compounds. Its chlorinated pyridine structure makes it valuable in cross-coupling reactions during medicinal chemistry research.
