CZE Determination of Calixarenes and Related Derivatives Using Acetonitrile as a Modifier

The applications of third-generation host compound calixarenes have been restricted due to their high price and shortage of supply. To obtain high pure calixarenes with high yield, synthesis strategy and analytical method investigations are necessary. The present work describes capillary zone electrophoresis (CZE) for the separation and determination of calixarene derivatives under the optimized CZE conditions within 20 min. The CZE method was evaluated with linear ranges, detection limits, recoveries and repeatability. The results indicated that the method was accurate and reproducible. As expected, it could be utilized to separate and evaluate calixarene derivatives during their synthesis and purification.
