Vitamin D4-d₅  (Synonyms: 22-Dihydroergocalciferol-d₅)

Vitamin D4-d₅ is the deuterium labeled Vitamin D4. Vitamin D4 (22-Dihydroergocalciferol) is a Vitamin D derived from fungi. The precursor of Vitamin D4 is 22,23-dihydroergosterol^[1].

1. This compound can be used as a tracer.
2. This compound can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.

Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs^[1].
