Levomefolic acid-¹³C,d₃  (Synonyms: 5-MTHF-¹³C,d₃)

Levomefolic acid-¹³C,d₃is the deuterium labeledLevomefolic acid(HY-14781)^[1]. Levomefolic acid (5-MTHF) is an orally active, brain-penetrant natural active form of folic acid and is one of the most widely used folic acid food supplements^[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].
