Recommanded Product: 1-Bromoundecane. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 1-Bromoundecane, is researched, Molecular C11H23Br, CAS is 693-67-4, about Amphiphilic Star-Shaped Calix[4]resorcinarene as Stationary Phase for Capillary Gas Chromatography.

This work describes the separation performance of the amphiphilic star-shaped calix[4]resorcinarene (C4A-CL)(I) as the stationary phase for capillary gas chromatog. (GC). The statically coated C4A-CL capillary column exhibited medium polarity and high column efficiency of 3877 plates m-1 determined by naphthalene at 120 °C. Importantly, the C4A-CL column exhibited extremely high resolving capability for aliphatic analytes with varying polarity, including n-alkanes, esters, ketones, alcs., and bromoalkanes. In addition, the C4A-CL column exhibited high selectivity and resolving capability for positional, structural and cis-/trans-isomers. Among them, the C4A-CL column displayed advantageous resolving capability over the com. DB-17 column for aromatic amine isomers. Moreover, it was applied for the determination of isomer impurities in real samples, showing good potential in GC applications.
In some applications, this compound(693-67-4)Recommanded Product: 1-Bromoundecane is unique.If you want to know more details about this compound, you can contact with the author or consult more relevant literature.
