Levonorgestrel-d6

Levonorgestrel-d6 is intended for use as an internal standard for the quantification of levonorgestrel (Cay-10006318) by GC- or LC-MS. Levonorgestrel is a synthetic progestin and the biologically active component of norgestrel (Cay-10006319). In vivo, levonorgestrel (60 µg/day) suppresses estrus and pregnancy in female cats. Post-coital insertion of subdermal levonorgestrel (5 mg pellet) implants prevents uterine implantation of embryos in mice. Formulations containing levonorgestrel have been used as contraceptives.Formal Name: (17alpha)-13-ethyl-17-hydroxy-18,19-dinorpregn-4-en-20-yn-3-one-2,2,4,6,6,10-d6. CAS Number: 2376035-98-0.
