Abstract

Abstract Cetyltrimethylammonium bromide (cetrimide) and tetrabutylammonium chloride were employed as ion-pairing reagents in reversed-phase ion-pair chromatography. The optimization of the retention and selectivity for some N-phenylamides of benzoylacetic acid was carried out by changing the content of the organic modifier (methanol) and the concentration of the ion-pairing reagent in the mobile phase.
