Description

Diethyl Oxalate-13C2 is a stable isotope-labeled analog of diethyl oxalate, where both carbonyl carbon atoms are replaced with the carbon-13 isotope. This compound is essential for advanced analytical and research applications where precise molecular tracking and quantification are required. It is primarily utilized by researchers and manufacturers in the pharmaceutical, agrochemical, and analytical chemistry sectors for use as an internal standard in mass spectrometry, metabolic pathway studies, and the synthesis of labeled complex molecules.

Application

• Internal standard for the quantitative analysis of oxalate and related compounds via Gas Chromatography-Mass Spectrometry (GC-MS) and Liquid Chromatography-Mass Spectrometry (LC-MS).
• Critical reagent in the synthesis of carbon-13 labeled pharmaceuticals and agrochemicals for drug metabolism and pharmacokinetics (DMPK) studies.
• Tracer compound in metabolic flux analysis and biochemical pathway research.
• Precursor for the preparation of other isotopically labeled intermediates and fine chemicals.
• Use in nuclear magnetic resonance (NMR) spectroscopy as a labeled standard.
• Application in environmental testing for the detection and quantification of oxalate derivatives.
