Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of nicotinic receptor agonists and antagonists. It serves as a building block in the development of drugs targeting neurological disorders such as Alzheimer's and Parkinson's diseases. Also employed in agrochemical synthesis for creating selective herbicides and insecticides due to its ability to modify bioactive molecules. Its oxidized pyridine structure enhances reactivity in coupling reactions, making it valuable in medicinal chemistry for constructing complex heterocyclic systems.
