A model is proposed for the derivatization mechanism of carboxylic acids with a fluorescent label, 4-bromomethyl-7-methoxycoumarin, in an aqueous non-ionic micellar system with the use of a tetraalkylammonium ion-pairing cation. Using experimentally

The on-line use of micellar phase-transfer catalysis is described for the automated reversed-phase high-performance liquid chromatographic (RP-HPLC) determination of free fatty acids in plasma; minimum manual sample handling is involved. After diluti

The potential of micellar liquid chromatography and of an on-line surfactant-mediated sample clean-up, which involves column-switching prior to conventional reversed-phase high-performance liquid chromatography, has been evaluated for the determinati

The effects of aqueous micellar systems on the derivatization of a fatty acid, 10-undecenoic acid (UA), with a flourophore, 4-bromomethyl-7-methoxycoumarin (BrMMC), were examined. High derivatization rates were obtained in solutions of the non-ionic

Micellar phase-transfer catalysis (MPTC) offers the opportunity to derivatize carboxylic acids directly in an aqueous matrix without prior extraction of the acids into a suitable aprotic solvent. The currently developed MPTC system consists of a non-

Two cases are added to those previously reported. Since most observers reporting one case have reported several, it is probable that the condition is not so rare as might be supposed from the rarity of its appearance in the literature.
