Scopolamine-d3 hydrobromide is the deuterium labeled Scopolamine hydrobromide. It is a high-affinity muscarinic antagonist capable of crossing the blood-brain barrier and competitively antagonizes 5-HT3 receptors with an IC50 of 2.09 μM. This compound can induce cognitive and memory deficits in animals and is utilized in research for preventing postoperative nausea and vomiting, motion sickness, and nervous system diseases. Stable heavy isotopes like hydrogen and carbon are incorporated into drug molecules primarily as tracers for quantitation during drug development.

• Serves as a tracer.
• Can be used as an internal standard for quantitative analysis through NMR, GC-MS, or LC-MS.
• Deuteration has potential to influence the pharmacokinetic and metabolic profiles of drugs.
