It is a metabolite of estradiol and a selective estrogen receptor beta (ER-beta) agonist. It has a role as an estrogen receptor agonist, a human urinary metabolite and an estrogen. It is a 16alpha-hydroxy steroid, a 17alpha-hydroxy steroid and a 3-hydroxy steroid. It derives from a hydride of an estrane."}]
