Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic receptor agonists and antagonists. Commonly employed in the production of drugs targeting neurological disorders such as Alzheimer's, Parkinson's, and schizophrenia. Also utilized in agrochemicals for the creation of novel pesticides due to its ability to interact with insect nervous systems. Its chloro and ester functional groups allow for easy modification in multi-step organic syntheses, making it valuable in medicinal chemistry research and development.
