Identification:

Chemical Name: Fumaric Acid

Synonyms: Fumarsäure; Trans-butenedioic acid

CAS No.: 110-17-8

Molecular Formula: C4H4O4

E-Code: E297

Properties:

White, odorless granules or crystalline powder. It is soluble in alcohol, slightly soluble in water and in ether, and very slightly soluble in chloroform.

Application:

As food sourness agent,fumaric acid plays an important role in bacteriostasis and antisepsis ,which is used as acidity regulator acidulant,temperature resistance oxidation assistant ,bloat accelerant and flavor fumaric acid is the intermediate for fine chemicals like medicament and optics bleacher and so forth in medicament industry, it is used to produce the alexipharmic sodium sodium dimercaptosuccinate and the ferrous fumarate that cures microcyte anemia.Fumaric acid is also used to produce unsaturated polyester resin and also is the main raw material of producing L-aspartic acid.
