Diethyl fumarate Chemical Properties,Usage,Production

Chemical Properties

colourless liquid

Uses

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

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

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.

Production Methods

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

Definition

ChEBI: A dieter obtained by the formal condensation of fumaric acid with ethanol.
