Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of antihypertensive drugs and other bioactive molecules. It serves as a building block in agrochemicals for developing herbicides and pesticides due to its reactive functional groups. Commonly employed in organic synthesis to introduce nitro and chloro substituents onto pyridine rings, facilitating further transformations through nucleophilic substitution or reduction reactions. Also utilized in research settings for developing novel heterocyclic compounds with potential medicinal properties.
