Sudan III-d₆  (Synonyms: Sudan Red III-d₆; Tetrazobenzene-β-naphthol-d₆; 111440 Red-d₆)

Sudan III-d₆ (Sudan Red III-d₆; Tetrazobenzene-β-naphthol-d₆) is a deuterium labeled Sudan III (HY-D0931). Sudan III is a hydrophobic bisazo dye^[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].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
