What is Diethyl maleate？

Diethyl maleate is a colorless and transparent liquid at normal temperature and pressure, insoluble in water, but soluble in ethanol and ether. Diethyl maleate is a maleate ester formed by the formal condensation of two carboxyl groups of maleic acid with ethanol. It is a thiol-reactive α,β-unsaturated carbonyl compound that can consume glutathione in exposed cells. glycopeptide.
