Description

Propionic Acid-Od is a deuterated isotopologue of propionic acid, where hydrogen atoms are replaced with deuterium, a stable isotope. This compound is essential for advanced analytical and research applications where isotopic labeling is required to study reaction mechanisms, metabolic pathways, or to serve as an internal standard. It is particularly valuable for researchers and quality control laboratories in the pharmaceutical, agrochemical, and academic sectors who require high-purity, isotopically labeled materials for mass spectrometry (MS) and nuclear magnetic resonance (NMR) spectroscopy.

Application

• As an internal standard for the quantitative analysis of propionic acid and related compounds via Gas Chromatography-Mass Spectrometry (GC-MS) or Liquid Chromatography-Mass Spectrometry (LC-MS).
• As a tracer molecule in metabolic studies and pharmacokinetic research within pharmaceutical development.
• For mechanistic studies in organic synthesis and catalysis, utilizing deuterium labeling to track hydrogen/deuterium exchange and reaction pathways.
• In the development and validation of analytical methods where a stable isotopically labeled analog is required for accuracy.
• As a precursor or building block in the synthesis of other deuterium-labeled fine chemicals and active pharmaceutical ingredients (APIs).
• For NMR spectroscopy as a solvent or analyte where deuterium labeling simplifies spectral interpretation.
