| Colorless and transparent liquid, miscible with many organic solvents, partially soluble in benzene and chloroform, and dissolves 1.4% in water at 30℃. Water dissolves 1.9% in diethyl maleate. It forms an azeotropic mixture with 88.2% water, with an azeotropic point of 99.65℃. 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. | |||||||||
