Description

Methyl-13C Sulfoxide is a stable isotope-labeled analog of dimethyl sulfoxide (DMSO), where one methyl group is enriched with carbon-13. This compound is essential for advanced analytical research, providing a non-radioactive tracer for precise metabolic and mechanistic studies. It is a critical reagent for scientists in pharmaceutical development, environmental analysis, and academic research requiring high-fidelity isotopic labeling for Nuclear Magnetic Resonance (NMR) spectroscopy and Mass Spectrometry (MS).

Application

• NMR Spectroscopy Solvent & Reference Standard: Used as an internal chemical shift reference and a deuterated solvent in high-resolution NMR studies.
• Metabolic Pathway Tracing: Serves as a 13C-labeled precursor to track biochemical pathways and metabolite flux in living systems.
• Mass Spectrometry Internal Standards: Employed for quantitative analysis via LC-MS or GC-MS to ensure accuracy and correct for instrument variability.
• Pharmaceutical Research & Development: Utilized in drug metabolism and pharmacokinetics (DMPK) studies to elucidate the fate of drug molecules.
• Chemical Reaction Mechanism Studies: Acts as a labeled reagent to investigate reaction intermediates and kinetics in synthetic chemistry.
• Environmental Fate Studies: Applied to trace the degradation and transformation of chemical compounds in environmental samples.
