Desmethylcitalopram-d₄ hydrochloride  (Synonyms: DCIT-d₄ hydrochloride)

Desmethylcitalopram-d₄ hydrochloride is deuterated labeled Desmethylcitalopram hydrochloride (HY-113739). Desmethylcitalopram (DCIT) hydrochloride is the active metabolite of Citalopram (HY-121203). Desmethylcitalopram has antidepressant effects. Desmethylcitalopram also inhibits cytochrome P450-2D6, -2C19 with IC₅₀s of 39.5 and 53.5 μM^[1].

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].
