Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of nicotinic receptor agonists and antagonists. It serves in the development of drugs targeting neurological disorders such as Alzheimer's, Parkinson's, and schizophrenia. Also employed in agrochemicals for the formulation of novel insecticides due to its structural affinity to nicotinoids. Its nitrile and chloro functionalities allow for versatile chemical modifications, making it valuable in medicinal chemistry research and development.
