Used as a key intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the development of herbicides and plant growth regulators. Its ester functionality and pyridine ring make it valuable for constructing complex molecules through nucleophilic substitution or coupling reactions. Commonly employed in research settings for modifying bioactive compounds to enhance stability, solubility, or target specificity. Also utilized in the preparation of nicotinic acid derivatives, which have applications in crop protection and medicinal chemistry.
