  •  Structural Formula:

  • Ethynodiol Diacetate CAS:297-76-7

  • Etynodiol diacetate (sold as Continuin, Femulen, Luteonorm, Luto-Metrodiol, and Metrodiol), or ethynodiol diacetate (USAN, BAN, JAN), also known as norethindrol diacetate or 3β-hydroxynorethisterone diacetate, is a steroidal progestin of the 19-nortestosterone group which is used as a hormonal contraceptive.It is the 3β,17β-diacetate ester of etynodiol, and acts as a rapidly converted prodrug to norethisterone,with etynodiol occurring as an intermediate. Etynodiol diacetate has weak androgenic activity, and, unlike most progestins but similarly to norethisterone and noretynodrel,also has some estrogenic activity.
