Description
Crotonaldehyde (2-butenal, β-methyl acrolein, propylene aldehyde) is similar in structure to acrolein, as both are α,β-unsaturated aldehydes. This structural similarity leads to similar sensitizing and irritating properties of the two compounds. Crotonaldehyde is used industrially in the preparation of other chemicals (chiefly sorbic acid), flavoring agents, and can form endogenously and in the environment.Crotonaldehyde is used in the manufacture ofbutyl alcohol, butyraldehyde, and in severalorganic synthesis.
