    Product Description

    Desogestrel-13C2-d2 is intended for use as an internal standard for the quantification of desogestrel (Item No. 23651) by GC- or LC-MS. Desogestrel is a synthetic progestogen.1 It inhibits ovulation and prevents fertilization in rabbits and mice. Desogestrel inhibits rhodamine 123 (Item No. 16672) efflux, a measure of P-glycoprotein activity, ex vivo in human lymphocytes and CD8+ T cells in a dose-dependent manner.2 Formulations containing desogestrel have been used as oral contraceptives and for the treatment of polycystic ovary syndrome.

    WARNING This product is not for human or veterinary use.
