Spectrophotometric Determination of Ephedrine Hydrochloride and Phenylephrine Hydrochloride

Journal of AOAC INTERNATIONAL, 1982
Abstract A method is described for quantitative determination of the sympathomimetic amines ephedrine HCl and phenylephrine HCl. The method is based on the interaction of N-alkylvinylamine formed from the condensation of the free secondary amine group and acetaldehyde with chloranil to give a vinylaminosubstituted quinone.
