colourless liquid
[Uses]

Diethyl Fumarate is a reagent in the preparation of chiral hydroisoindolines via Diels-Alder cycloaddition which are potent, brain-penetrant, human neurokinin-1 receptor antagonists.
[Uses]

Diethyl fumarate is unsaturated polyester resins are used in applications, such as reinforced glass fiber for boats, piping, bathtubs, roof panels, etc., and as protective coatings, finishes, and lacquers.
[Uses]

It is used as a pesticide or comonomer for the production of polystyrene.
[Definition]

ChEBI: A dieter obtained by the formal condensation of fumaric acid with ethanol.
[Production Methods]

Diethyl fumarate is manufactured via esterification of ethanol with fumaric acid.
