Acrolein (2-Propanal)

Acrolein is a highly reactive, volatile, and flammable liquid chemical compound with a pungent, irritating odor. It's an unsaturated aldehyde, meaning it contains a carbon-carbon double bond and a carbonyl group. Acrolein is found in the environment as a byproduct of combustion (e.g., vehicle exhaust, wood and tobacco smoke) and can be produced industrially from propylene or by dehydrating glycerol. It's used in the production of various chemicals, as a herbicide, and as a biocide.
