Fumaric acid or trans-butenedioic acid is the chemical compound with the formula HO2CCH=CHCO2H. This white crystalline compound is one of two isomeric unsaturated dicarboxylic acids, the other being maleic acid. Fumaric acid has a fruit-like taste. As a food additive, it is used as an acidity regulator and is denoted by the E number E297. It is generally used in beverages and baking powders for which requirements are placed on purity. We offer Commercial pure, USP NF and FCC Food grade.
C4H4O4 — 116.07
2-Butenedioic acid, E-.
Fumaric acid [110-17-8].
Fumaric Acid contains not less than 99.5 percent and not more than 100.5 percent of C4H4O4, calculated on the anhydrous basis.
Identification: Dissolve about 10 mg in 25 mL of water, and to this solution add 1 mL of a solution prepared by mixing 20 mL of copper sulfate solution (1 in 5) and 8 mL of pyridine: a precipitate is formed in the blue solution within 1 minute.
Residue: not more than 0.1%.
Heavy metals: 0.001%.
Limit of maleic acid: To pass the test. Not more than 0.1% of maleic acid is found.
Organic volatile impurities: meets the requirements.
Assay: Transfer about 1 g of Fumaric Acid, accurately weighed, to a conical flask, add 50 mL of methanol, and warm gently on a steam bath to effect solution. Cool, add phenolphthalein TS, and titrate with 0.5 N sodium hydroxide VS to the first appearance of a pink color that persists for not less than 30 seconds. Perform a blank titration, and make any necessary correction. Each mL of 0.5 N sodium hydroxide is equivalent to 29.02 mg of C4H4O4.
