Ethinylestradiol
A synthetic oestrogen obtained in 1938 by Hans Herloff Inhoffen and Walter Hohlweg, in medical use since 1943. Since the 1960s it has been the oestrogen found in almost all combined contraceptive pills. This family brings together the active ingredient, pharmacopoeial impurities, metabolites, labelled standards and other impurities.
Did you know?Compared with natural oestradiol it resists breakdown by the liver much better, thanks to an ethinyl group with a carbon-carbon triple bond: this is why it works when taken by mouth.
