Product name: Fumaric acid
English alias: 2-Butenedioicacid(2Z)-,dioctylester;2-Butenedioicaciddioctylester;DIOCTYLMALEATE;DOM;(Z)-2-Butenedioicaciddioctylester;2-ChemicalbookButenedioicacid(Z)-,dioctylester,DioctylMaleate;2-Butenedioicacid(2Z)-,1,4-dioctylester;2-Butenedioicacid(Z)-,dioctylester
CAS: 110-17-8
Molecular formula:C4H4O4
Appearance: White fine crystalline powder
Package: 200kg/drum
The substance precipitated from water forms monoclinic needle-like, prismatic, or leaf-shaped white crystals or crystalline powder. Odorless with a distinct sour taste approximately 1.5 times stronger than citric acid. Melting point 287°C, boiling point 290°C. Sublimes above 200°C; dehydrates to maleic anhydride at 230°C when heated. Boiling with water yields DL-malic acid. Soluble in ethanol, slightly soluble in water and diethyl ether, and sparingly soluble in chloroform. A 3% aqueous solution has a pH of 2.0–2.5 and exhibits strong buffering capacity, maintaining the solution's pH around 3.0.

1.Food Additive (E297): Fumaric acid used as an acidulant and flavor enhancer in beverages, baked goods, and confectionery due to its strong sourness and low hygroscopicity.
2.Pharmaceutical Intermediate: Fumaric acid serves as a key intermediate in the synthesis of pharmaceuticals, including antiretroviral drugs and iron supplements.
3.Polymer and Resin Production:Fumaric acid Used in the manufacture of unsaturated polyester resins (UPR) and alkyd resins to improve hardness and chemical resistance.
4.Animal Feed Additive: Fumaric acid acts as an acidifier in animal feed to promote gut health and improve nutrient absorption.
5.Industrial Chemical: Fumaric acid Employed in electroplating solutions, cleaning agents, and as a mordant in dyeing processes.
Dioctyl Maleate may cause mild irritation to skin and eyes. Appropriate personal protective equipment including gloves and safety glasses is recommended during handling. Avoid prolonged or repeated contact. The product is biodegradable and has low environmental impact when properly handled.
Store in a cool, dry, well-ventilated area away from moisture and incompatible substances (e.g., strong bases).
Keep containers tightly sealed to prevent caking and contamination.
Avoid dust formation during handling and storage.
Fumaric acid is supplied in 25 kg multi-layer paper bags or 500 kg jumbo bags with inner polyethylene lining. All packages comply with international transport regulations for non-hazardous materials. Custom packaging options are available upon request.
