Used as a key intermediate in the synthesis of agrochemicals, particularly herbicides and insecticides. Its structure allows for the introduction of picolinoyl moieties, enhancing the biological activity of active ingredients. Commonly employed in the development of chloro-substituted pyridine derivatives, which show efficacy in crop protection. Also utilized in the preparation of pharmaceuticals where pyridine-based scaffolds are required for target modulation. Its ester functionality enables easy transformation into amides or acids for further derivatization in both agricultural and medicinal chemistry.
