A new simple and sensitive spectrophotometric method was developed on the basis of a colour reaction of cefoperazone sodium with Folin Ciocalteu's phenol reagent in presence of sodium carbonate, and it is stable for 20 min. The method is based on the formation of blue coloured chromophore that has an absorption maxima at 668 nm and obeys Beer's law in the concentration range of 8/40 µg/ml. Results of the analysis were validated statistically and by recovery studies. The method was found to be suitable for routine determination of cefoperazone sodium.
