The Use of Spectrophotometric and Thermodynamic Methods for the Determination of Glibenclamide

For the assay of glibenclamide, a spectrophotometric and thermodynamic method is defined. The technique involves a glibenclamide charge transfer complexion reaction with 2,3-Dichloro-5,6-Dicyano-1,4-benzoquinone (DDQ) to form a very intense coloured charge transfer complex with a 1:1 stoichiometric ratio. Under tailored
