Abstract

A simple and sensitive spectroscopic method was developed for the estimation of CEFAD in pharmaceutical dosage forms. This method is based on CEFAD, showing absorbance at 257 nm in methanol. This method obeys Beers law in the concentration range of 10 to100 µg mL-1 respectively. The proposed method is precise, accurate and reproducible and can be extended to the analysis of CEFAD in bulk and tablet formulations.
