Stilbestrol, or stilboestrol, also known as 4,4'-dihydroxystilbene or 4,4'-stilbenediol, is a stilbenoid nonsteroidal estrogen^[1] and the parent compound of a group of more potent nonsteroidal estrogen derivatives that includes, most notably, diethylstilbestrol (DES).^[1]^[2]^[3] The term "stilbestrol" is often used incorrectly to refer to DES, but they are not the same compound.^[2]

Stilbestrol itself is an active estrogen but is less potent than DES and other derivatives.^[1]
