Medchemexpress LLC Diphenhydramine-d6 hydrochloride | 1189986-72-8 | 99.3% | 5 MG
Diphenhydramine-d6 hydrochloride is the deuterium-labeled form of Diphenphenhydramine hydrochloride, a first-generation histamine H1-receptor antagonist with anti-cholinergic effects. It can cross the ovine blood-brain barrier (BBB). Stable heavy isotopes of hydrogen, carbon, and other elements are incorporated into drug molecules primarily as tracers for quantitation during drug development. Deuteration, specifically, has gained attention for its potential to impact the pharmacokinetic and metabolic profiles of drugs.
- Can be used as a tracer.
- Can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.
