Sequential injection spectrophotometric determination of ritodrine hydrochloride using 4-aminoantipyrine.

Abstract

A sequential injection spectrophotometric determination of ritodrine hydrochloride is described. The method is based on the condensation of aminoantipyrine with phenols in the presence of an alkaline oxidizing agent to yield a pink coloured product the absorbance of which is monitored at 503nm. Different sequential injection analysis (SIA) parameters… (More)
