General description

25-hydroxyvitamin D3 (calcifediol) is a prohormone produced via hydroxylation of vitamin D3 (cholecalciferol) in the liver. It is a precursor for the synthesis of calcitriol or 1,25-dihydroxyvitamin D3 or [1,25(OH)2D3]. It is used as a biomarker to determine the status of vitamin D in the body.
25-Hydroxyvitamin D3 (6,19,19-d3) is a deuterated vitamin D3 wherein C-6 and C-19 protons are replaced by deuterium.

Application

25-Hydroxyvitamin D3 (6,19,19-d3) can be used as an analytical standard.

Simultaneous and accurate measurement of vitamin D and 25-hydroxyvitamin D in biological samples is a barrier limiting our ability to define "optimal" vitamin D status. Thus, our goal was to optimize conditions and evaluate an LC-MS method for simultaneous detection
