Resumo

The applicability of the spectrophotometric method for the quantitative determination of phenazepam using methyl red as an optical reference sample is demonstrated. The optical parameters of methyl red’s absorption bands and its optimum regions of absorption are confirmed, a scaling ratio is determined, and equations for the calibration curves are proposed.
