Methy-d3 (toluenesulfonate) is the deuterium labeled Methy toluenesulfonate[1]
Medchemexpress LLC Nonan-1-ol-d19 | 349553-86-2 | 98.0% | 163.37 | 5 MG
Nonan-1-ol-d19 is a deuterium-labeled version of Nonan-1-ol. It is intended for research use only and is not sold to patients. The compound appears as a colorless to light yellow liquid. It should be stored at -20°C for up to 3 years in pure form, and in solvent at -80°C for 6 months or -20°C for 1 month.
- Can be used as a tracer.
- Suitable as an internal standard for quantitative analysis using techniques such as NMR, GC-MS, or LC-MS.
- Deuterium substitution has the potential to influence the pharmacokinetic and metabolic profiles of drugs.
Medchemexpress LLC Itraconazole-d5 | 1217510-38-7 | 99.55% | 710.66 | 1 MG
Itraconazole-d5 is the deuterium labeled Itraconazole. Itraconazole (R51211) is a triazole antifungal agent and a potent and orally active Hedgehog (Hh) signaling pathway antagonist with an IC50 of ~800 nM. Itraconazole potently inhibits lanosterol 14α-demethylase (cytochrome P450 enzyme), thereby inhibiting the oxidative conversion of lanosterol to ergosterol. Itraconazole has anticancer and antiangiogenic effects. For research use only. We do not sell to patients.
- Compound can be used as a tracer.
- Compound can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.
- Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs.
Medchemexpress LLC Biotin-d2-1 | 1217481-41-8 | 99.65% | 5 MG
Biotin-d2-1 is the deuterium labeled Biotin. Biotin is an enzyme co-factor present in minute amounts in every living cell.
- This compound can be used as a tracer.
- This compound 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, 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.

Medchemexpress LLC Taurocholic acid-d4 sodium | 2410279-93-3 | 98.2% | 1 MG
Taurocholic acid-d4 (sodium) is the deuterium-labeled version of Taurocholic acid, which is a bile acid involved in the emulsification of fats. It is intended for research use only and is not sold to patients. This compound can be utilized as a tracer and as an internal standard for quantitative analysis through methods like NMR, GC-MS, or LC-MS. Deuteration, the incorporation of stable heavy isotopes like hydrogen and carbon into drug molecules, is used as a tracer for quantitation during drug development and has the potential to influence the pharmacokinetic and metabolic profiles of drugs.
- Deuterium labeled Taurocholic acid.
- Involved in the emulsification of fats.
- Can be used as a tracer.
- Can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.
