Both properties of maleic acid can be explained on account of the intramolecular hydrogen bonding that takes place at the expense of intermolecular interactions. Maleic acid, also called cis-butenedioic acid (HO 2 CCH=CHCO 2 H), unsaturated organic dibasic acid, used in making polyesters for fibre-reinforced laminated moldings and paint vehicles, and in the manufacture of fumaric acid and many other chemical products.Maleic acid and its anhydride are prepared industrially by the catalytic oxidation of benzene. Molecular Weight. A substance identified primarily by an EC or list number may be linked with more than one CAS number, or with CAS numbers that ... and there is sufficient information available in ECHA’s databases for ECHA’s algorithms to generate a molecular structure. Fumaric acid is a weak organic acid containing two carboxylic acid functional groups and as a result it has two PKa values, PKa1 = 3.03 and PKa2 = 4.44. as an antioxidant.

The molecular structure is based on structures generated from information available in ECHA’s databases. OD. 1, L -tryptophan is zwitterionic, as are most amino acids in the solid state, and fumaric acid … Maleic acid, or cis-butenedioic acid, is a geometric isomer of fumaric acid; it melts at about 140°C;. Among the side-effects are leucopenia and lymphopenia. Compare Products: Select up to 4 products. Summary: This gene encodes a member of the lyase 1 family. Fumaric acid esters (FAE), also known as fumarates, are ester derivatives of fumaric acid. EC Number 203-743-0. Search results for fumaric acid at Sigma-Aldrich. This, coupled with the fact that mild hydrolysis of maleic anhydride (MAnh) leads to maleic acid, is linked to the cis structure of maleic acid and to the trans structure of fumaric acid … Maleic acid is soluble in water whereas fumaric acid is not and the melting point of maleic acid (130 - 131 degree centigrade) is also much lower than that of fumaric acid (287 degree centigrade).

Among the side-effects are leucopenia and lymphopenia. We successfully obtained good quality hard golden-yellow single crystals of L-tryptophan fumaric acid monohydrate, and we report herein on its synthesis and crystal structure. It has also been used in film-coated pellet formulations as an acidifying agent and also to increase drug solubility.
Structure, properties, spectra, suppliers and links for: Fumaric acid, 110-17-8. The key difference between maleic acid and fumaric acid is that maleic acid is the cis-isomer of butenedioic acid, whereas fumaric acid is the trans-isomer.. Maleic acid and fumaric acid are carboxylic acids.They are cis-trans isomers of each other. Pesticide properties for fumaric acid, including approvals, environmental fate, eco-toxicity and human health issues Molecular Formula. cis-butenedioic acid (sĭs-byo͞o'tēndī`ōĭk), IUPAC name for maleic acid; see fumaric acid fumaric acid or trans-butenedioic acid, HO 2 CCH=CHCO 2 H, unsaturated dicarboxylic acid that melts at 287°C;. It also forms within human skin when that skin is exposed to sunlight. It is formed by the oxidation of succinic acid by succinate dehydrogenase.
