Abstract

A rapid and simple spectrophotometric method for the detn. of sulpha drugs was described. The method is based on the formation of a red colored azo product by the diazotization of sulfonamides, sulfamethoxazole, sulfadiazine and sulfacetamide followed by a coupling reaction with resorcinol. Absorbance of the resulting red azo product is measured at 500 nm. Beer's law is obeyed in the concn. range of 0.25-7.0 μg/mL at the wavelength of max. absorption. The method was successfully employed for the detn. of sulfonamides in various pharmaceutical prepns. [on SciFinder(R)]
