Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of nicotinic receptor agonists and pesticides. It serves as a building block in the preparation of complex organic molecules due to its reactivity in oxidation and coupling reactions. Its N-oxide functionality enhances solubility and directs regioselective substitution in aromatic rings, making it valuable in fine chemical manufacturing. Also employed in research for catalyst design and in the production of specialty polymers.
