Used as a key intermediate in the synthesis of agrochemicals, particularly in the production of neonicotinoid insecticides. It contributes to the development of crop protection agents due to its ability to modify biological activity in target molecules. Also employed in the preparation of pharmaceuticals where nicotinic acid derivatives show potential in medicinal chemistry. Its chloro and methyl substituents, along with the carboxylic acid functionality, allow for further chemical modifications, making it valuable in organic synthesis and research settings.
