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.Kawamoto, Naoki; Hu, Yongxing; Kuwahara, Yutaka; Ihara, Hirotaka; Takafuji, Makoto researched the compound: 11-Bromoundecanoic acid( cas:2834-05-1 ).Product Details of 2834-05-1.They published the article 《A molecular shape recognitive HPLC stationary phase based on a highly ordered amphiphilic glutamide molecular gel》 about this compound( cas:2834-05-1 ) in Nanomaterials. Keywords: amphiphilic glutamide mol gel shape HPLC stationary phase; high performance liquid chromatography (HPLC); highly-oriented structure; molecular gels; phenolic compounds; stereo isomers; steroids. We’ll tell you more about this compound (cas:2834-05-1).
Chiral glutamide-derived lipids form self-assembled fibrous mol. gels that can be used as HPLC organic phases. In this study, HPLC separation efficiency was improved through the addition of branched amphiphilic glutamide lipids to the side chains of a terminally immobilized flexible polymer backbone. Poly(4-vinylpyridine) with a trimethoxysilyl group at one end was grafted onto the surface of porous silica particles (Sil-VP15, polymerization degree = 15), and the pyridyl side chains were quaternized with a glutamide lipid having a bromide group (BrG). Elemental anal. indicated that the total amount of the organic phase of the prepared stationary phase (Sil-VPG155) was 38.0 wt%, and the quaternization degree of the pyridyl groups was determined to be 32.5%. Differential scanning calorimetric anal. of a methanol suspension of Sil-VPG15 indicated that the G moieties formed a highly ordered structure below the phase transition temperature even on the silica surface, and the ordered G moieties exhibited a gel-to-liquid crystalline phase transition. Compared with a com. available octadecylated silica column, the Sil-VPG15 stationary phase showed high selectivity toward polycyclic aromatic hydrocarbons, and particularly excellent separations were obtained for geometrical and positional isomers. Sil-VPG15 also showed highly selective separation for phenol derivatives, and bio-related mols. containing phenolic groups such as steroids were successfully separated These separation abilities are probably due to multiple interactions between the elutes and the highly ordered functional groups, such as the pyridinium and amide groups, on the highly ordered mol. gel having self-assembling G moieties.
