Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of nicotinic receptor modulators and other central nervous system agents. It serves as a building block in agrochemicals for developing herbicides and insecticides due to its pyridine core, which enhances bioactivity. Commonly employed in medicinal chemistry for structure-activity relationship studies, especially in optimizing compounds targeting neurological disorders. Its ester and chloro functionalities allow for easy modification through nucleophilic substitution and hydrolysis, enabling diverse derivatization in drug discovery programs.
