Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of nicotinic acid derivatives. It serves as a building block in the preparation of active ingredients in crop protection agents due to its reactive ester and nitro functional groups. Also employed in research for heterocyclic compound development, especially in creating pyridine-based structures with biological activity. Its nitro group allows for further functionalization through reduction to amine, enabling diverse derivatization pathways in medicinal chemistry.
