Medchemexpress LLC Thiamphenicol-d3 | 2211914-19-9 | 99.5% | 5 MG
Thiamphenicol-d3 is a deuterium labeled Thiamphenicol, a broad-spectrum antimicrobial antibiotic. It inhibits protein synthesis by binding to the 50S ribosomal subunit, resulting in a bacteriostatic effect against Gram-negative, Gram-positive aerobic, and anaerobic bacteria. This compound is 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
- Stable heavy isotopes of hydrogen, carbon, and other elements incorporated into the drug molecule
- Potential to affect the pharmacokinetic and metabolic profiles of drugs due to deuteration
Medchemexpress LLC n-Nonadecane-d40 | 39756-36-0 | 100 MG
n-Nonadecane-d40 is a deuterium labeled Nonadecane intended for research use only. Deuteration, the incorporation of stable heavy isotopes of hydrogen (deuterium) into drug molecules, has the potential to influence the pharmacokinetic and metabolic profiles of drugs.
- Utilized as a tracer
- Functions as an internal standard for quantitative analysis
- Suitable for methods such as NMR, GC-MS, or LC-MS
Cayman Chemical RebamIpIde-d4 1mg
An internal standard for the quantification of rebamipide by GC- or LC-MS
