It is soluble in ethanol (5.*6g/**0g,*0℃), slightly soluble in water (0.*3g/**0ml,*5℃) and in ether, and very slightly soluble in chloroform. It has no hygroscopicity, and will sublime at **0℃. Boiling point: **0℃ (decompose). It will turn to maleic anhydride at **0℃, and will generate DL-malic acid if boiled with water.

Usage:
Fumaric acid has bacteriostatic and antiseptic function. It can be used as acidulant, acidity regulator, acidifier, thermal-oxidative resist auxiliary, curing accelerant and spice. Widly used in producing various carbonic acid drink, wine, concentrated solid drink, ice cream and other cold foods and drink. It can replace malic acid, citric acid, for its acidity degree is 1.5 times of that of citric acid. Fumaric acid can be used as pharmaceutical intermediate and optical bleaching agent, also used in manufacturing unsaturated polyester resin.
