So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Keough, T. researched the compound: cis-Cyclohexane-1,2-dicarboxylic acid( cas:610-09-3 ).Reference of cis-Cyclohexane-1,2-dicarboxylic acid.They published the article 《Probing molecular structure by the chemical resolution of hydrogen migrations》 about this compound( cas:610-09-3 ) in Organic Mass Spectrometry. Keywords: mass spectra chem ionization methylation; stereoisomerism mass spectra cyclohexanedicarboxylic acid; regioisomerism mass spectra hydroxybenzoic acid. We’ll tell you more about this compound (cas:610-09-3).
MeCl chem.-ionization mass spectroscopy, involving a methylation technique based on the chem. resolution of H migrations, gives ionic fragments which differentiate cis and trans isomers. The method differentiates 1,2-cyclohexanedicarboxylic acids but fails (as do protonation methods) to differentiate 1,2-cyclohexanediols. The utility of methylation in conjunction with mass spectra/mass spectra techniques in distinguishing the regioisomerism of HOC6H4CO2H is discussed.
Although many compounds look similar to this compound(610-09-3)Reference of cis-Cyclohexane-1,2-dicarboxylic acid, numerous studies have shown that this compound(SMILES:O=C([C@H]1[C@@H](C(O)=O)CCCC1)O), has unique advantages.
