Used as a key intermediate in the synthesis of agrochemicals, particularly herbicides and insecticides, due to its reactive chlorine and nitrile functional groups. Its structure allows for easy modification in multi-step reactions, making it valuable in developing nicotinic acid derivatives. Also employed in the preparation of pharmaceuticals where substituted pyridines are required, especially in compounds targeting nervous system receptors. Commonly utilized in research for building complex heterocyclic systems in crop protection agents.
