Estradiol
The main and most potent oestrogen in the body, produced mostly by the ovaries: it regulates the menstrual cycle and the development of female sexual characteristics and protects the bones. It was isolated in the mid-1930s and is used in hormone replacement therapy. This family brings together the active ingredient, pharmacopoeial impurities, metabolites, labelled standards and other impurities.
Did you know?To isolate its first crystals, in 1935, Edward Doisy's group in the United States had to process about four tonnes of sow ovaries, obtaining just a few milligrams.
