Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic receptor modulators and central nervous system agents. It serves as a building block in agrochemicals for the production of herbicides and insecticides due to its reactive chloro and ester functionalities. The methoxy and chloro substituents allow for selective functionalization, enabling fine-tuning of biological activity in drug design. Commonly employed in cross-coupling reactions and nucleophilic substitutions to introduce the nicotinate core into larger bioactive molecules.
