Folinic acid-d₄ calcium hydrate  (Synonyms: Leucovorin-d4 calcium hydrate)

Folinic acid-d₄-1 (Leucovorin-d₄-1) calcium hydrate is deuterated labeled Folinic acid (HY-17556). Folinic acid (Leucovorin) is a biological folic acid and is generally administered along with Methotrexate (HY-14519) as a rescue agent to decrease Methotrexate-induced toxicity.

1. This compound can be used as a tracer.
2. This compound can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.

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].
