Levonorgestrel-d6 is intended for use as an internal standard for the quantification of levonorgestrel by GC- or LC-MS. Levonorgestrel is a synthetic progestin and the biologically active component of norgestrel .1 In vivo, levonorgestrel (60 μg/day) suppresses estrus and pregnancy in female cats.2 Post-coital insertion of subdermal levonorgestrel (5 mg pellet) implants prevents uterine implantation of embryos in mice.3 Formulations containing levonorgestrel have been used as contraceptives. | [References]
