Dihydrouracil-¹³C₄,¹⁵N₂  (Synonyms: 5,6-Dihydrouracil-¹³C₄,¹⁵N₂)

Dihydrouracil-¹³C₄,¹⁵N₂ is the ¹³C and ¹⁵N labeled Dihydrouracil[1]. Dihydrouracil (5,6-Dihydrouracil), a metabolite of Uracil, can be used as a marker for identification of dihydropyrimidine dehydrogenase (DPD)-deficient[2][3].

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].
