p-Cresol sulfate-d7 (potassium) is the deuterium labeled p-Cresyl sulfate potassium. p-Methylphenyl potassium sulfate is a prototype protein-bound uremic toxin[1][2].
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].
