meso-Butestrol (developmental code name SC-3402), also known as 2,3-bis(4-hydroxyphenyl)butane, is a synthetic nonsteroidal estrogen which was never marketed.[1][2][3][4][5][6][7] It is a so-called "short-acting" or "impeded" estrogen.[1][2][3][5][4][6][7] meso-Butestrol is structurally related to diethylstilbestrol and other stilbestrols.[8] The fully potent counterpart to meso-butestrol is meso-hexestrol, analogously to the relationship of dimethylstilbestrol to diethylstilbestrol.[3]
