Used as a key intermediate in the synthesis of nicotinic acid derivatives, particularly in the production of agrochemicals and pharmaceuticals. It serves as a building block for pyridine-based compounds, which are important in the development of herbicides and insecticides. Its chloro and ester functional groups allow for further chemical modifications, enabling the introduction of various substituents to tailor the biological activity of the final product. Commonly employed in research and industrial settings for constructing complex heterocyclic systems with pesticidal properties.
