Vitamin D Standards - New Chemistry
Stable isotope labeled Vitamin D standards were pioneered by IsoSciences. Current derivatives that are available include the active Vitamin D3 metabolite 25-Hydroxyvitamin D3-[2H3] (cholicalciferol-d3; CAS 140710-94-7), with deuterium at the preferred 6,19,19 positions. The strategic location of deuterium atoms allows deuterium to be retained in the daughter ions of the compound, allowing a improved diagnostic analysis.
The patent pending methodology employed by IsoSciences is used to prepare all the Vitamin D compounds, yielding high incorporation of deuterium. Additionally, the preparations minimize or eliminate the presence of any unlabeled compound that would otherwise interfere with your mass spectroscopic assay.
