Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of nicotinic receptor agonists and antagonists. It plays a role in developing drugs for neurological disorders such as Alzheimer's and schizophrenia. Also employed in agrochemicals for the creation of herbicides and insecticides due to its ability to modify bioactive molecules. Its aldehyde functional group allows for easy derivatization, making it valuable in medicinal chemistry for building complex heterocyclic systems.
