General description

Mechanisms of the isomerization processes of molecular and anionic diethylstilbestrol (DES) has been reported. Estrogen activity of cis- and trans-diethylstilbestrol has been evaluated. Diethylstilbestrol is a carcinogenic synthetic estrogen.

Application

Diethylstilbestrol was used as internal standard for the analysis of drug residues in urine of rats and calves by on-line HPLC with ultraviolet and continuous-flow fast atom bombardmentmass spectrometry detectors.
