Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of nicotinic receptor modulators and treatments for neurological disorders. Commonly employed in the development of smoking cessation aids due to its structural similarity to nicotine. Also utilized in agrochemicals for the formulation of selective pesticides, leveraging its bioactivity in insect nervous systems. Frequently applied in research settings for the creation of novel pyridine-containing compounds with potential therapeutic effects.
