20beta-Dihydrodydrogesterone-D7 (major)

20beta-Dihydrodydrogesterone-D7 (major) is a steroid hormone that has been used in medical research to investigate the effects of progesterone on the human body. It is a deuterated form of 20beta-Dihydrodydrogesterone, which means it has seven deuterium atoms instead of hydrogen atoms. This makes it useful for studying the metabolism and distribution of progesterone in the body, as deuterium is a stable isotope that can be traced using mass spectrometry. Studies have shown that 20beta-Dihydrodydrogesterone-D7 (major) has similar biological activity to natural progesterone, meaning it can bind to progesterone receptors in the body and exert similar effects. These effects include regulation of the menstrual cycle, maintenance of pregnancy, and preparation of the uterus for implantation of a fertilized egg. It has also been investigated for use in hormone replacement therapy for menopausal women. Chemically, 20beta-Dihydrodydrogesterone-D7 (major) is a synthetic derivative of progesterone, with a similar structure and chemical formula. Its molecular weight is 314.52 g/mol, and it has a melting point of around 124-128°C. It is soluble in organic solvents such as ethanol and chloroform, but insoluble in water. Overall, 20beta-Dihydrodydrogesterone-D7 (major) is a valuable tool for medical researchers studying the effects of progesterone on the body, and may have potential applications in hormone replacement therapy. Its stable isotope labeling also makes it useful for tracing the metabolism and distribution of progesterone in the body.
