Product Name:Fumaric acid
English Name:Fumaric acid
CAS No.:110-17-8
Aliases:trans-Butenedioic acid, (E)-2-Butenedioic acid, Allomaleic acid, Boletic acid, trans-1,2-Ethylenedicarboxylic acid
Molecular Formula:C4H4O4
Physical Properties:Colorless monoclinic needles or small leaf-like crystals with a fruity acid taste. Melting point 298-300 °C (sublimes), boiling point approximately 137.07 °C, density 1.62 g/cm³, vapor pressure 1.7 mmHg (165 °C), flash point 230 °C, refractive index 1.5260, pKa 3.02 and 4.38 (25 °C), pH 2.1 (4.9 g/L water, 20 °C), water solubility 0.63 g/100 mL (25 °C). Slightly soluble in water, ether, and acetic acid; soluble in ethanol; almost insoluble in chloroform. Stable at room temperature, decomposes at approximately 230 °C. Incompatible with strong oxidizing agents, bases, and reducing agents. Combustible.
Uses:Used as a food acidulant, usually in combination with citric acid, in beverages, fruit candies, jellies, ice cream, and other food products. Also used in the manufacture of unsaturated polyester resins, pesticides, amino acids, and fine chemical intermediates. Serves as a mordant, antioxidant, and primary standard for standardizing alkali solutions.
