17-Desacetyl Norgestimate-d7 (Mixture of Isomers)

17-Desacetyl Norgestimate-d7 is a mixture of isotopically labeled isomers of the synthetic progestin norgestimate. It is used as a reference standard in the analysis of norgestimate in biological samples. Norgestimate is a synthetic progestin that is commonly used in combination with estrogen as an oral contraceptive. It works by preventing ovulation, thickening cervical mucus, and altering the lining of the uterus to make it less receptive to fertilization. Norgestimate is a derivative of the natural hormone progesterone, and it is metabolized in the body to its active form, 17-desacetyl norgestimate. The isotopically labeled 17-desacetyl norgestimate-d7 is used as a reference standard in the analysis of norgestimate in biological samples. This is important for ensuring accurate measurements of norgestimate levels in patients taking oral contraceptives. The chemical properties of the isotopically labeled compound are identical to those of the unlabeled compound, except for the presence of deuterium atoms, which can be easily detected using mass spectrometry. In conclusion, 17-Desacetyl Norgestimate-d7 is an important tool for researchers and clinicians in the analysis of norgestimate in biological samples. Its chemical properties and isotopic labeling make it a reliable reference standard for accurate measurement of norgestimate levels in patients taking oral contraceptives.
