Folic Acid-d2 is the deuterium labeled Folic acid. Folic acid (Vitamin M; Vitamin B9) is a B vitamin; is necessary for the production and maintenance of new cells, for DNA synthesis and RNA synthesis.
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].
