Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Validation Study, Electrophoresis called Positional and geometrical anionic isomer separations by capillary electrophoresis-electrospray ionization-mass spectrometry, Author is Nogami, Chika; Sawada, Hirokazu, which mentions a compound: 610-09-3, SMILESS is O=C([C@H]1[C@@H](C(O)=O)CCCC1)O, Molecular C8H12O4, Product Details of 610-09-3.
Capillary electrophoresis-electrospray ionization-mass spectrometry (CE-ESI-MS) was applied to the anal. of polar positional and geometrical anionic isomers. Since the studied positional and geometrical anionic isomers have different pKa values, they could be separated by CE-ESI-MS under simple anal. conditions using a bare fused-silica capillary and volatile ammonium acetate buffer after optimizing buffer pH. Ortho-, meta-, para-hydroxybenzoate positional isomers were completely separated on a fused-silica capillary with 20 mM ammonium acetate buffer at pH 10.0, and cis-, trans-cyclohexane dicarboxylate geometrical isomers could be also separated with 20 mM ammonium acetate buffer at pH 4.0. Several anal. parameters affecting ESI-MS sensitivity were also studied. Both running buffer pH and sheath liquid pH had significant effects on the selectivity and the sensitivity on CE-ESI-MS anal. while sheath flow rate and other parameters had little influence. Under optimized conditions, linearity, detection limit, and repeatability of the anal. of hydroxybenzoate isomers were examined, and good results were obtained. The method presented in this paper is a simple, robust, and cost-effective method for simultaneous anal. of positional and geometrical anionic isomers and of other small anionic compounds
