QUICK LINKS

25-Hydroxy Vitamin D2-d6 is the labelled metabolite of Vitamin D2. Vitamin D2, also known as ergocalciferol, is one of the two main forms of vitamin D, the other being vitamin D3 (cholecalciferol). 25-Hydroxy Vitamin D2-d6 serves as an ideal internal standard for mass spectrometry-based assays due to its almost identical chemical and physical properties to the non-deuterated form, except for a slight difference in mass. This difference allows for the precise differentiation and quantification of the deuterated and non-deuterated molecules in complex biological matrices, leading to more accurate and reliable measurements of vitamin D levels.
