Etonogestrel (CAS NO.54048-10-1), its Synonyms are (17-alpha)-13-Ethyl-17-hydroxy-11-methylene-18,19-dinorpregn-4-en-20-yn-3-one ; 13-Ethyl-11-methylene-18,19-dinor-17-alpha-pregn-4-en-20-yn-3-one ; 13-Ethyl-17-hydroxy-11-methylene-18,19-dinor-17alpha-pregn-4-en-20-yn-3-one ; 17-Ethinyl-17-beta-hydroxy-18-methyl-11-methylene-4-estren-3-one ; 3-Keto-desogestrel ; 3-Ketodesogestrel ; 3-Oxodesogestrel ; Implanon . |
| Flash Point: | 201.1 oC |
| Usage: |
Etonogestrel is a molecule used in hormonal contraceptives, most notably the subdermal implant Implanon and the contraceptive vaginal ring NuvaRing. Etonogestrel, the specific progestin used in NuvaRing, is the active metabolite of the inactive prodrug desogestrel, one of two third-generation progestins found in some epidemiological studies of combined oral contraceptive pills to be associated with a higher risk of venous thrombosis than combined oral contraceptive pills containing certain second-generation progestins. |
