5α-Androstane-3β,17β-diol-[d4] (Dihydroepiandrosterone-d4)

5α-Androstane-3β,17β-diol-[d4] (Dihydroepiandrosterone-d4) is a deuterated version of the hormone Dihydroepiandrosterone (DHEA), which is produced naturally in the adrenal gland. DHEA is a precursor to both testosterone and estrogen and is known to have a significant impact on the body's endocrine system. Dihydroepiandrosterone-d4 is commonly used in medical research as a stable isotope-labeled internal standard for the quantification of endogenous DHEA levels in biological matrices. This allows for accurate measurement of DHEA levels in biological samples such as blood, urine, and saliva. In addition to research purposes, Dihydroepiandrosterone-d4 is also used in the pharmaceutical industry to develop new drugs that target the endocrine system. It is important to note that DHEA supplements are not regulated by the FDA and should only be taken under the guidance of a healthcare professional. From a chemical perspective, Dihydroepiandrosterone-d4 has a molecular weight of 287.49 g/mol and a molecular formula of C19H28D4O2. It is a white crystalline powder that is soluble in ethanol, methanol, and chloroform, and has a melting point of 145-147°C. Overall, Dihydroepiandrosterone-d4 is a valuable tool for medical research and drug development in the field of endocrinology.
