Pyridine-3-carbaldehyde, also known as nicotinaldehyde, is an organic compound with the formula C₅H₄NCHO. It is one of three isomeric pyridinaldehydes. The other isomers are pyridine-2-carboxaldehyde and pyridine-4-carboxaldehyde. It is a colorless liquid that is routinely available commercially. It can be produced from nicotinonitrile. Alternatively, it arises by the aerobic oxidation of the corresponding alcohol.^[1]

Safety

3-Pyridinecarboxaldehyde is a severe skin irritant.^[2]
