Separations of regio- and stereoisomers on p-tert-butylcalix[n]arene phases, Recommanded Product: 3-Methylpyrimidine-2,4(1H,3H)-dione, the publication is Journal of Chromatographic Science (1998), 36(8), 383-387, database is CAplus.
The chromatog. behavior of new calix[n]arene-bonded (n = 4, 6, 8) silica gels are described. Cavities of different size and shape are formed depending on the number of aromatic moieties. The differences in ring size were used to study chromatog. selectivities towards analytes of various substance classes, including disubstituted aromatics, uracil derivatives, and estradiol epimers. The authors’ results indicate that these calixarene-bonded phases show a high resolution power for regio- and stereoisomers.
