17beta-Estradiol-16,16-d2

17beta-Estradiol-16,16-d2 is a synthetic form of the hormone estrogen that is used in medical research and bioassays. It is a deuterated derivative of 17beta-estradiol, which means that two hydrogen atoms in the molecule have been replaced with deuterium, a stable isotope of hydrogen. This modification allows for more precise analysis and detection of the molecule in experiments. In terms of usage, 17beta-Estradiol-16,16-d2 is commonly used as an internal standard in various analytical assays, such as liquid chromatography-mass spectrometry (LC-MS) and gas chromatography-mass spectrometry (GC-MS). It is also used as a tracer molecule in metabolic studies, where researchers can track the metabolism and distribution of 17beta-Estradiol-16,16-d2 in biological systems. From a chemical standpoint, 17beta-Estradiol-16,16-d2 has the same molecular formula (C18H20D2O2) and structure as 17beta-estradiol, with the exception of the deuterium substitution. It is a steroid hormone that plays a key role in the regulation of the female reproductive system, as well as other physiological processes such as bone health and cardiovascular function. Overall, 17beta-Estradiol-16,16-d2 is a valuable tool for researchers in the fields of biochemistry, pharmacology, and endocrinology, allowing for more precise and accurate measurement and analysis of estrogen-related processes in the body.
