Molecular weight: 116.07

EINECS No.: 203-743-0

Chemical properties: monoclinic system, colorless acicular or lobular crystal, with the sour taste of fruit. Slightly soluble in water, ether and acetic acid, soluble in ethanol. Almost insoluble in chloroform.

Application: Food sour agent, which plays an important role in bacteriostasis and antisepsis; Acidity regulator, acidifier, anti thermal oxidation additive, curing accelerator, flavor When used as the gas-producing agent of solid beverage, the bubbles are long-lasting and delicate; Fine chemical intermediates such as medicine and optical bleach It is used in the production of antidote sodium dimercaptobutyrate and blood-rich iron for the treatment of small red blood cell anemia It is also used to produce unsaturated polyester resin.

Properties

Fumaric acid appears as a colorless crystalline solid. The primary hazard is the threat to the environment. Immediate steps should be taken to limit spread to the environment. Combustible, though may be difficult to ignite. Used to make paints and plastics, in food processing and preservation, and for other uses. Fumaric acid is a butenedioic acid in which the C=C double bond has E geometry. It is an intermediate metabolite in the citric acid cycle. It has a role as a food acidity regulator and a fundamental metabolite. It is a conjugate acid of a fumarate(1-).
