Methacrolein, or methacrylaldehyde, is an unsaturated aldehyde. It is a clear, colorless, flammable liquid that is present in cigarettes when smoking.[1]

Industrially, the primary use of methacrolein is in the manufacture of polymers and synthetic resins.

Exposure to methacrolein is highly irritating to the eyes, nose, throat and lungs.
