Triphenyliodoethylene (TPIE), also known as iodotriphenylethylene or as phenylstilbene iodide, as well as triphenylvinyl iodide, is a synthetic nonsteroidal estrogen of the triphenylethylene group that is related to triphenylchloroethylene and triphenylbromoethylene and was never marketed.[1][2][3]
