Estradiol dibenzoate (EDB), also known as estradiol 3,17β-dibenzoate, is an estrogen ester which was developed in the 1930s and was never marketed.^[1]^[2]^[3]^[4]^[5]^[6]^[7] It is the C3 and C17β benzoate diester of estradiol.^[1] Estradiol dibenzoate has a longer duration of action than estradiol benzoate (estradiol 3-benzoate) by depot injection.^[2]^[3]^[4]^[5]^[6]^[7]
