17β-Estradiol-2,4,16,16-d4 17-Pentanoate

17?-Estradiol-2,4,16,16-d4 17-Pentanoate is a synthetic form of 17?-Estradiol, which is the most potent form of estrogen in the human body. This compound is useful for research purposes in the fields of endocrinology and reproductive medicine. It is primarily used to study the mechanisms of estrogen activity and its role in biological processes such as cell growth, differentiation, and reproduction. Chemically, 17?-Estradiol-2,4,16,16-d4 17-Pentanoate is a deuterated form of 17?-Estradiol, meaning that it contains four deuterium atoms in the positions 2, 4, 16, and 16 of the estradiol molecule. These isotopic substitutions make it possible to track the compound's metabolic fate in living organisms and to distinguish it from other estrogen compounds. As a pentanoate ester, this compound is more lipophilic than the parent hormone, allowing it to be more easily absorbed by cells and tissues. This esterification also increases the compound's stability and prolongs its half-life in vivo. Overall, 17?-Estradiol-2,4,16,16-d4 17-Pentanoate is a valuable tool for studying the biological effects of estrogen and for developing new therapies for estrogen-related disorders. Its unique chemical properties make it an ideal candidate for research in the field of endocrinology and reproductive medicine.
