Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of nicotinic receptor agonists and antagonists. It plays an important role in the development of drugs targeting neurological disorders such as Alzheimer's and Parkinson's diseases. Also utilized in agrochemicals for the creation of novel pesticides and herbicides due to its reactive functional groups that allow for diverse chemical modifications. Its nitrile and chlorine moieties enable coupling reactions and heterocycle formation, making it valuable in medicinal chemistry and drug discovery research.
