Enantioselective analysis of omeprazole in pharmaceutical formulations by chiral high-performance liquid chromatography and capillary electrophoresis

Autor: Bonato Pierina S., Paias Fernanda O.

Publikováno v: Journal of the Brazilian Chemical Society, Vol 15, Iss 2, Pp 318-323 (2004)

We developed two sensitive and simple assay procedures based on high- performance liquid chromatography and capillary electrophoresis (CE) for the enantioselective analysis of omeprazole in pharmaceutical formulations. Rac-omeprazole and (S)-omeprazo
