Medchemexpress LLC Vortioxetine-d8 hydrobromide | 960203-27-4 | C18H15D8BrN2S | 1 MG
Vortioxetine-d8 hydrobromide, also known as Lu AA 21004-d8 hydrobromide, is a deuterated form of Vortioxetine. Vortioxetine acts as an antagonist of 5-HT3A and 5-HT7 receptors, and an inhibitor of the 5-hydroxytryptamine transporter (SERT). It also functions as a 5-HT1A agonist and a partial 5-HT1B agonist.

Medchemexpress LLC Isonicotinamide-d4 | 1219799-40-2 | 99.9% | 126.15 | 50 MG
Isonicotinamide-d4 is the deuterium labeled Isonicotinamide. It is intended for research use only and not for sale to patients. Stable heavy isotopes like deuterium have been incorporated into drug molecules for use as tracers in drug development, and deuteration has shown potential to influence the pharmacokinetic and metabolic profiles of drugs.
- Can be used as a tracer.
- Can be used as an internal standard for quantitative analysis using techniques such as NMR, GC-MS, or LC-MS.
Medchemexpress LLC p-Tolualdehyde-d7 | 1219805-23-8 | 98.2% | 127.19 | 50 MG
p-Tolualdehyde-d7 is the deuterium labeled p-Tolualdehyde. p-Tolualdehyde is an active small molecule that could be used as a drug intermediate. 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.
- Can be used as a tracer.
- Can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.
