Used as a key intermediate in the synthesis of agrochemicals, particularly herbicides and plant growth regulators. Its structure allows for further functionalization in the development of chlorinated nicotinic derivatives with biological activity. Also employed in the production of pharmaceuticals where nicotinic acid derivatives are required, especially in compounds targeting metabolic or inflammatory pathways. Commonly utilized in research settings for designing novel heterocyclic compounds due to its reactive chlorine sites and carboxylic acid group, enabling coupling reactions and derivatization.
