In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Amphiphilic Star-Shaped Calix[4]resorcinarene as Stationary Phase for Capillary Gas Chromatography, published in 2019-11-30, which mentions a compound: 693-67-4, Name is 1-Bromoundecane, Molecular C11H23Br, Computed Properties of C11H23Br.
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.
