Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic receptor modulators and anti-inflammatory agents. It serves as a building block in agrochemicals for creating herbicides and insecticides due to its reactive chloro and nitro functional groups. The ester moiety allows for easy modification in multi-step organic syntheses, making it valuable in medicinal chemistry research. Commonly employed in the preparation of pyridine-based compounds with biological activity.
