Abstract

A simple, rapid and direct spectrophotometric method for the determination of fluorouracil in presence of its alkali-induced degradation products is presented. The method is based on measuring the absolute value of 1D and 2D of the absorption curve at the chosen wavelengths. The validity of the method was confirmed using laboratory prepared mixtures of the intact drug with its alkali-induced degradation products. The method has been also applied for the assay of some pharmaceutical preparations. Moreover, alkaline degradations has been studied and a derivative spectrophotometric method for quantitative determination of these degradations, even in presence of the intact molecule is presented.
