Description

Oxalic [2H]Acid is a deuterated derivative of oxalic acid, where specific hydrogen atoms are replaced with the stable isotope deuterium. This compound is essential for advanced research and analytical applications where isotopic labeling is required to study reaction mechanisms, metabolic pathways, or to serve as an internal standard. It is particularly valuable for scientists and industries engaged in nuclear magnetic resonance (NMR) spectroscopy, mass spectrometry, and pharmaceutical development.

Application

• NMR Spectroscopy Solvent & Reagent: Used as a deuterated acid or shift reagent in nuclear magnetic resonance studies.
• Mass Spectrometry Internal Standard: Serves as a stable isotope-labeled internal standard for precise quantitative analysis.
• Mechanistic & Metabolic Studies: Employed as a tracer to elucidate chemical reaction pathways and biological metabolism.
• Pharmaceutical Research: Utilized in the development and testing of deuterated drug compounds.
• Specialty Chemical Synthesis: Acts as a building block for synthesizing other deuterium-labeled complex molecules.
• Analytical Chemistry: Applied in calibration and method development for various chromatographic and spectroscopic techniques.
