Abstract

The sodium salt of the single-isomer, chiral resolving agent, octakis(2,3-diacetyl-6-sulfo)-gamma -cyclodextrin (ODAS-gamma CD) has been used for thecapillary electrophoretic separation of the enantiomers of alkylarylphosphates which carry a phosphorus-based stereogenic center. The effective mobilities and separation selectivities were measured at different ODAS-gamma CDand methanol concentrations to find the conditions under which the minor enantiomers could be adequately quantitated in samples obtained by chemical resolution of the racemic mixtures. This work extends the utility of ODAS-gamma CD to a hitherto unexplored field, the capillary electrophoretic separation of the enantiomers of organophosphorus compounds.
