Description

General description

Acrolein is a metabolite that is generated by catabolic pathaways via many oxidases.

Acrolein causes transient urothelial loss and exposes local afferent terminals to a toxic environment.

Application

Acrolein has been used in the preparation of monomeric and dimeric β-hydroxypropionaldehyde in a hydration reaction.
