Reserpine-d9 is the deuterium labeled Reserpine. Reserpine is an inhibitor of the vesicular monoamine transporter 2 (VMAT2). Deuteration can affect the pharmacokinetic and metabolic profiles of drugs. This compound is for research use only, not sold to patients.
- Used as a tracer.
- Used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.
Medchemexpress LLC Citric acid-d4 | 147664-83-3 | 196.15 | 25 MG
Citric acid-d4 is the deuterium labeled Citric acid (HY-N1428). Citric acid is a natural preservative and food tartness enhancer. It induces apoptosis and cell cycle arrest at G2/M phase and S phase in HaCaT cells. Citric acid can cause oxidative damage of the liver by decreasing antioxidative enzyme activities. It is also an acidulant, emulsifier, sequestrant, and buffering agent widely used across many industries. This product is for research use only and not sold to patients.
- Can be used as a tracer.
- 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, primarily as tracers for quantitation during drug development.
- Deuteration has garnered attention due to its potential to affect the pharmacokinetic and metabolic profiles of drugs.

Medchemexpress LLC L-Carnitine-d9 chloride | 2687961-04-0 | 99.0% | 5 MG
L-Carnitine-d9 chloride is a deuterium-labeled L-Carnitine chloride. This highly polar, small zwitterion serves as an essential co-factor for the mitochondrial β-oxidation pathway, facilitating the transport of long-chain fatty acyl-CoAs into mitochondria for degradation. It also functions as an antioxidant and can alleviate metabolic imbalances in various inborn errors of metabolism.
- Can be used as a tracer.
- Can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.
- Deuteration offers potential to influence pharmacokinetic and metabolic profiles of drugs.
