Isotopically Labeled Compounds
Medchemexpress LLC 16:0-18:1 PA-d31 sodium | 474943-59-4 | 99.0% | 728.10 | 1 MG
16:0-18:1 PA-d31 (sodium) is deuterium labeled 16:0-18:1 PA (sodium). It is for research use only and not sold to patients. 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.

It preserves the pharmacological profile of vilazodone (a serotonin selective reuptake inhibitor and 5-HT1A receptor partial agonist) and is intended primarily as an internal standard for LC-MS quantitation and related research applications.
- Deuterium-labeled analogue (d8) suitable as an internal standard.
- High purity, 99.0%.
- Molecular formula C26H19D8N5O2; molecular weight 449.57 g/mol.
- Available in small research pack sizes appropriate for analytical workflows.
- Stable when stored as powder at -20°C or 4°C for specified durations.
- Solubility in water ≥ 0.32 mg/mL (0.71 mM), compatible with common LC solvents.
Medchemexpress LLC Carboplatin-d4 | 41575-94-4 | 99.0% | 375.28 | 5 MG
Carboplatin-d4 is the deuterium labeled Carboplatin. It is a DNA synthesis inhibitor that binds to DNA, inhibits replication and transcription, and induces cell death. This compound is a derivative of CDDP and a potent anti-cancer agent, intended for research use only.
- Can be used as a tracer.
- Can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.
Medchemexpress LLC Atazanavir-d6 | 1092540-50-5 | 99.3% | 710.89 | 1 MG
Atazanavir-d6 is a deuterium-labeled variant of Atazanavir (BMS-232632), a highly selective HIV-1 protease inhibitor. It was the first protease inhibitor approved for once-daily administration. Atazanavir-d6 acts as a substrate and inhibitor of CYP3A4, and also inhibits and induces P-glycoprotein (P-gp). It has also been identified as a SARS-CoV 3CLpro inhibitor with an IC50 of 3.49 μM. Deuterium labeling incorporates stable heavy isotopes into the drug molecule, which can impact pharmacokinetic and metabolic profiles and serve as tracers for quantitative analysis.
- Used as a tracer
- Used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS
