Not to be confused with diethylstilbestrol.

Stilbestrol, or stilboestrol, also known as 4,4'-dihydroxystilbene or 4,4'-stilbenediol, is a stilbenoid and the parent compound of a group of non-steroidal estrogens that includes, most notably, diethylstilbestrol.

The stilbestrol estrogens include diethylstilbestrol, diethylstilbestrol dipropionate, benzestrol, dienestrol, dienestrol acetate, dimestrol (dimethoxydiethylstilbene), fosfestrol (diethylstilbestrol diphosphate), furostilbestrol, hexestrol (dihydrodiethylstilbestrol), hexestrol diacetate, hexestrol dicaprylate, hexestrol diphosphate, hexestrol dipropionate, mestilbol (diethylstilbestrol monomethyl ether), methestrol (promethestrol; dimethylhexestrol), methestrol dipropionate (promethestrol dipropionate), among others. The stilbestrol estrogens bind with high affinity to both ERα and ERβ.

Resveratrol is a stilbenoid with estrogenic properties that is not a silbestrol derivative (it is 3,4',5-stilbenetriol).

The term "stilbestrol" is very often used incorrectly to refer to diethylstilbestrol.
