Abstract

Analytical difficulties in the analysis of D&C Red No. 21 by column chromatography are overcome by using an ascending paper chromatographic technique, based on that of Graichen, followed by elution of the zones and spectrophotometric determination. Results compare well with those by column chromatography.
