The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: cis-Cyclohexane-1,2-dicarboxylic acid( cas:610-09-3 ) is researched.Product Details of 610-09-3.Yang, Ying; Wu, Rui; Huang, Shaohua; Bai, Zhengwu published the article 《Silica sol assisted chromatographic NMR spectroscopy for resolution of trans- and cis-isomers》 about this compound( cas:610-09-3 ) in Journal of Magnetic Resonance. Keywords: silica soluble cisisomer transisomer chromatog NMR resolution; Chromatographic NMR spectroscopy; DOSY; Isomer; Resolution; Silica sol. Let’s learn more about this compound (cas:610-09-3).
Chromatog. NMR spectroscopy can seperate the mixtures of species with significantly different mol. size, but generally fails for isomeric species. Herein, we reported the resolution of trans- and cis-isomers and their structural analog, which are different in mol. shapes, but similar in mass, were greatly enhanced in the presence of silica soluble The mixtures of maleic acid, fumaric acid and succinic acid, and the mixtures of trans- and cis-1,2-cyclohexanedicarboxylic acids, were distinguished by virtue of their different degrees of interaction with silica soluble Moreover, we found mixed solvents could improve the spectral resolution of DOSY spectra of mixtures
From this literature《Silica sol assisted chromatographic NMR spectroscopy for resolution of trans- and cis-isomers》,we know some information about this compound(610-09-3)Product Details of 610-09-3, but this is not all information, there are many literatures related to this compound(610-09-3).
