Ercalcidiol-d3（Cat No.:S000546） is a specialized form of ercalcidiol, also known as 25-hydroxyvitamin D3, a major circulating metabolite of vitamin D. The “d3” designation indicates that three hydrogen atoms in the ercalcidiol molecule are replaced with deuterium, a stable isotope of hydrogen. This isotopic labeling facilitates precise tracking of ercalcidiol metabolism and its pharmacokinetics using advanced analytical techniques like mass spectrometry. Ercalcidiol-d3 serves as a valuable tool in clinical and pharmacological studies, aiding in elucidating vitamin D metabolism, understanding its bioavailability, and investigating its role in various health conditions, including bone health and immune function.
