Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of nicotinic receptor agonists and antagonists. Commonly employed in the preparation of pyridyl-containing compounds for drug development. Also utilized in agrochemicals to create pesticides and herbicides due to its ability to modify bioactive molecules. Serves as a building block in organic synthesis, especially in cross-coupling reactions and nucleophilic substitutions for introducing pyridylmethyl groups.
