Estradiol 17β-benzoate (E2-17B ) is an estrogen and an estrogen ester —specifically, the C17β benzoate ester of estradiol —which was never marketed.[ 1] [ 2] [ 3] positional isomer of the better-known and clinically used estradiol ester estradiol benzoate (estradiol 3-benzoate; Progynon-B).[ 1] [ 4]
