Estradiol - Nature

Open Data Verified Data

This product is white or milky white crystalline powder; Odorless. Dissolved in dioxane, acetone, slightly soluble in ethanol, insoluble in water. The melting point was 175-180 °c. Specific rotation 75.~82.
estradiol is a natural estrogen secreted in the body mainly by mature ovarian follicles. The effect is similar to that of diethylstilbestrol. It can promote the development of sexual organs, and make the endometrial hyperplasia, shedding, produce periodic menstruation, can inhibit the anterior pituitary gland secretion of gonadotropin and prolactin, and against estrogen.
