Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic receptor agonists and other central nervous system agents. It serves as a building block in agrochemicals for the production of certain herbicides and insecticides due to its stable pyridine ring structure. Also employed in research laboratories for the preparation of functionalized pyridine derivatives used in catalysis and material science. Its nitro group allows for further chemical modifications, enabling the introduction of amino or other functional groups through reduction or substitution reactions.
