5β-Dihydrocortisol-d6

5β-Dihydrocortisol-d6 is a deuterated version of the hormone 5β-dihydrocortisol, which is also known as cortolone. This hormone is a metabolite of cortisol, which is a steroid hormone produced by the adrenal gland in response to stress. 5β-Dihydrocortisol-d6 is commonly used as an internal standard in steroid hormone analysis, specifically for the determination of cortisol and cortisone in biological samples. The chemical formula of 5β-Dihydrocortisol-d6 is C21H26D6O4, and it has a molecular weight of 346.49 g/mol. It is a white crystalline powder that is soluble in ethanol and methanol, but insoluble in water. This compound is stable under normal conditions of use and storage. When used as an internal standard, 5β-Dihydrocortisol-d6 is added to biological samples in a known quantity before analysis. This allows for accurate quantification of cortisol and cortisone levels in the sample. It is commonly used in research studies to investigate the role of cortisol and cortisone in various physiological processes, such as stress response, inflammation, and metabolism. Overall, 5β-Dihydrocortisol-d6 is a useful tool in steroid hormone analysis and research, providing accurate and reliable results in the investigation of the role of cortisol and cortisone in various physiological processes.
