Dicarboxylic acid

Dicarboxylic acids are organic compounds that contain two functional carboxylic acid (–COOH) groups. Industrially, they are important in producing polyester, polyols, polyamides, and nylon and as a precursor to active pharmaceutical ingredients and additives. Dicarboxylic acids are important water-soluble components of atmospheric aerosols. Succinic,

Long-chain dicarboxylic acids

Journal of Colloid and Interface Science, 1977
Abstract Aqueous dispersions of heavy-metal salts of 5-(and 6-)carboxy-4-hexyl-2-cyclohexen-1-yl octanoic acids, denoted by H2D, were prepared by direct mixing of solutions of the metal nitrates with solutions of Na2D. With any particular concentration of D2− ion, it was found that the turbidity increased sharply when the concentration of a metal ion

Rat liver metabolism of dicarboxylic acids

American Journal of Physiology-Gastrointestinal and Liver Physiology, 1989
Recently, we demonstrated in rat liver that dicarboxylic acids containing more than five carbons can be activated by a microsomal dicarboxylyl-CoA synthetase (J. Vamecq, E. de Hoffmann, and F. Van Hoof. Biochem. J. 230: 683-693, 1985). The products of this reaction, dicarboxylyl-CoA esters, were found to be substrates for an H2O2-generating ...

Dicarboxylic Acid Dipeptide Neutral Endopeptidase Inhibitors

Journal of Medicinal Chemistry, 1995
The synthesis of three series of dicarboxylic acid dipeptide neutral endopeptidase 24.11 (NEP) inhibitors is described. In particular, the amino butyramide 21a exhibited potent NEP inhibitory activity (IC50 = 5.0 nM) in vitro and in vivo. Blood levels of 21a were determined using an ex vivo method by measuring plasma inhibitory activity in conscious ...

5,8-Dimethoxynaphthalene-1,6-dicarboxylic Acid

Acta Crystallographica Section C Crystal Structure Communications, 1997
The title compound, C14H12O6, crystallized in the centrosymmetric space group Pbca but does not exhibit hydrogen bonding of the usual cyclic dimer type about a center of symmetry or otherwise. Each molecule is linked to six neighbors by eight hydrogen bonds, which leads, in this structure, to a rich pattern of chains.

Enantioselective Synthesis of Diamino Dicarboxylic Acids

The Journal of Organic Chemistry, 1999
The preparation of alkyl diamino dicarboxylic acids with high optical purity (100% ee, >98.5% de) and high yields based on asymmetric catalytic hydrogenation is described. The required prochiral precursors are prepared from dialdehydes and Z-, Boc-, and acetyl-protected phosphonoglycines.

Complexation and sensing of dicarboxylate anions and dicarboxylic acids

Coordination Chemistry Reviews, 2015
Abstract The relevance of dicarboxylate anions and dicarboxylic acids in biological and industrial processes requires that such species are easily detected and quantified. In this regard, the research about synthetic receptors, which can offer a straightforward analytical signal, has produced significant advances in the last decades.

Organotellurium derivatives of dicarboxylic acids

Journal of Organometallic Chemistry, 1976
Abstract The freshly prepared sodium salts of ortho-phthalic acid and tetrabromo ortho-phthalic acid react with diaryltellurium dichlorides in chloroform to afford new dimeric organotellurium carboxylates, R2Te(C8X4O4)2 (X = H, Br). The new compounds contain fourteen membered rings and the detailed structure is discussed particularly in the light of ...
