Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic receptor ligands and other central nervous system agents. It serves as a building block in agrochemicals for creating herbicides and insecticides due to its stable aromatic structure and reactivity. Also employed in the preparation of functional materials, including organic semiconductors and liquid crystals, where the chloro and phenyl groups facilitate further cross-coupling reactions. Its pyridine core allows for metal coordination, making it useful in catalysis and coordination chemistry.
