[Product
name]: Fumaric Acid
[CAS No.]:*******8
[Chemical formula]: C4H4O4
[Chemical molecular weight]: **6.*7
[Physical properties]: Colorless or white crystal
or powder, soluble in water and ethanol, slightly
soluble in cold water,

Product Description:
Fumaric acid, a carboxylic acid derived from
butene, is a colorless and flammable crystal. It
is the simplest unsaturated dicarboxylic acid.
Also known as fumaric acid or fumaric acid. It
was first found in Corydalis yanhusuo. In
addition, it also exists in a variety of
mushrooms and fresh beef. Fumaric acid and maleic
acid are geometric isomers of each other. Fumaric
acid is transformed into maleic acid when heated
to ******0 ºC. Fumaric acid can also produce
monobasic and binary esters or amides, but it can
not produce monobasic acyl chloride. It reacts
with phosphorus pentachloride or thionyl chloride
to form binary acyl chloride. Trans maleic acid
is oxidized by potassium permanganate to form
racemic tartaric acid.

Fumaric acid uses :
Fumaric acid, as a food sour agent, plays an
important role in bacteriostasis and
anti-corrosion. It is used as acidity regulator,
acidifier, anti thermal oxidation assistant,
curing accelerator and spice. Fumaric acid is an
intermediate of fine chemicals such as medicine
and optical bleach. In the pharmaceutical
industry, it is used for the production of
antidote sodium dimercaptobutyrate and blood rich
iron for the treatment of small red blood cell
anemia. Fumaric acid is also used to produce
unsaturated polyester resin and is also the main
raw material for the production of L-aspartic
acid.
