Medchemexpress LLC Actinine-d9 chloride | 85806-17-3 | 98.0% | 190.72 | 1 MG
Actinine-d9 chloride is the deuterium labeled Actinine chloride. Actinine chloride is an angiopathic substance produced as an intermediary metabolite by gut microbiota that feed on carnitine in dietary red meat. 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.
