Used as a key intermediate in the synthesis of agrochemicals, particularly herbicides and insecticides, due to its reactive chloro and ester functional groups. Its structure allows for easy modification in multi-step reactions, making it valuable in developing active ingredients that target specific plant or pest systems. Commonly employed in the creation of nicotinic acid derivatives, which show biological activity in crop protection products. Also utilized in research for developing new pharmaceutical agents, especially those involving heterocyclic compounds with potential therapeutic effects.
