The effects of the addition of TRIS(cas 77-86-1) on the separation of diethylstilbestrol and its decomposition products

A new method for the determination of diethylstilbestrol by nonaqueous capillary electrophoresis was developed in this paper. The method was applied to the separation of diethylstilbestrol and its decomposition products by using methanol as solvent and sodium acetate as electrolyte. The effects of the addition of TRIS(cas 77-86-1) on the separation of diethylstilbestrol and its decomposition products were studied. The methanol solution of Tris(cas 77-86-1)-2 5mmol /L sodium acetate was used as the electrophoretic medium, diethylstilbestrol and its dissociation. The method was applied to the determination of the content of the active ingredient in diethylstilbestrol tablets, and the results were satisfactory.
