Estradiol undecylenate (EUe; developmental code name SH-368)^[1] is an estrogen medication and estrogen ester which was never marketed.^[2] It is the C17β undecenoate (undecylenate) ester of estradiol.^[2] Following an intramuscular injection, EUe has a very prolonged effect, exceeding that of other estradiol esters like estradiol valerate and estradiol enanthate.^[3] Due to its very long duration of action, EUe releases only subthreshold amounts of estradiol at conventional doses.^[3] However, this may still be useful in menopausal hormone therapy.^[3]
