Norethindrone-d6

Norethindrone-d6 is intended for use as an internal standard for the quantification of norethindrone (Cay-20941) by GC- or LC-MS. Norethindrone is a synthetic progestin. In vivo, norethindrone (0.5 mg/animal per day) inhibits the estrous cycle in female mice. It induces tumor progression and metastasis in a BT474 breast cancer mouse xenograft model. Formulations containing norethindrone have been used as oral contraceptives.Formal Name: 17alpha-hydroxy-19-norpregn-4-en-20-yn-3-one-2,2,4,6,6,10-d6. CAS Number: 2376036-05-2.
