Chemical Information
FooDB NameDiethylstilbesterol
DescriptionDiethylstilbestrol, also known as DES, belongs to the class of organic compounds known as stilbenes. These are organic compounds containing a 1,2-diphenylethylene moiety. Stilbenes (C6-C2-C6 ) are derived from the common phenylpropene (C6-C3) skeleton building block. The introduction of one or more hydroxyl groups to a phenyl ring lead to stilbenoids. Diethylstilbestrol is an extremely weak basic (essentially neutral) compound (based on its pKa). Diethylstilbestrol is found, on average, in the highest concentration within gram beans. This could make diethylstilbestrol a potential biomarker for the consumption of these foods. Diethylstilbestrol is formally rated as a carcinogen (by IARC 1) and is also a potentially toxic compound.
