Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic receptor modulators and other bioactive compounds. Its aldehyde functional group allows for easy derivatization, making it valuable in forming imines, oximes, or undergoing reduction to produce alcohol derivatives for further chemical transformations. Commonly employed in medicinal chemistry for constructing heterocyclic systems with potential neurological activity. Also utilized in agrochemical research for developing novel active ingredients due to its pyridine backbone, which is known for favorable metabolic stability and binding properties.
