Crotonaldehyde is a clear, colorless to straw colored liquid with a strong, suffocating odor. It is highly flammable and produces toxic vapors at room temperature. Crotonaldehyde is found naturally in emissions of some vegetation and volcanoes; many foods contain crotonaldehyde in small amounts. 

Crotonaldehyde, stabilized appears as a clear colorless to straw colored liquid with a penetrating pungent odor.

Very toxic by inhalation.
May polymerize with the release of heat under exposure to heat or contamination. If polymerization takes place inside a container, the container may rupture violently.

Less dense than water. Vapors heavier than air.

Crotonaldehyde has the aldehydic group at the C-1 position and −C=C− at the position at C-2 with 4 carbon atoms in the parent chain, thus the name is But-2-en-1-al.

Crotonaldehyde is mainly used in the manufacture of sorbic acid, which is a yeast and mold inhibitor. Crotonaldehyde has been used as a warning agent in fuels, as alcohol denaturant, as stabilizer for tetraethyl-lead, in the preparation of rubber accelerators, and in leather tanning.

Crotonaldehyde is an unsaturated aldehyde with commercial applications, including the manufacture of sorbic acid, that is also found in tobacco smoke, gasoline and diesel engine exhausts, and smoke from wood burning. Airborne exposure to this chemical can cause eyes, nose, throat, and lung irritation.
