Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic receptor agonists and antagonists. Plays a role in the production of agrochemicals, including insecticides and herbicides, due to its ability to form complex heterocyclic structures. Also utilized in research for creating novel nitrogen-containing compounds with potential biological activity. Its cyano and ester functional groups allow for diverse chemical transformations, making it valuable in medicinal chemistry and drug discovery.
