Estrone-d4（Cat No.:S000821） is a deuterated variant of estrone, where four hydrogen atoms are replaced with deuterium, resulting in the molecular formula C18H18D4O2. This stable isotope-labeled form of estrone is extensively used in analytical chemistry, particularly in mass spectrometry and nuclear magnetic resonance (NMR) spectroscopy. It serves as an internal standard for precise quantification and detailed study of estrogen metabolism. Estrone-d4 is crucial in pharmaceutical research and clinical diagnostics, providing insights into hormone-related disorders and the pharmacokinetics of hormone therapies, especially in studies related to women’s health and endocrine disorders.
