Description

Sodium Propionate-13C3 is a stable isotope-labeled analog of sodium propionate, where all three carbon atoms are the carbon-13 isotope. This compound is essential for advanced analytical research, providing an internal standard for precise quantification and metabolic pathway tracing using techniques like mass spectrometry and NMR. It is a critical material for researchers and quality control laboratories in the pharmaceutical, food safety, and life science sectors requiring high-fidelity isotopic purity.

Application

• Internal Standard for Mass Spectrometry (MS): Used as a quantitative reference standard in LC-MS and GC-MS analysis of propionate and related metabolites in complex biological matrices.
• Metabolic Pathway Tracing: Enables the study of propionate metabolism, absorption, and utilization in nutritional, microbiological, and pharmacological research.
• NMR Spectroscopy: Serves as a labeled probe for structural elucidation and dynamic studies in chemical and biochemical research.
• Pharmaceutical Development: Employed in drug metabolism and pharmacokinetics (DMPK) studies for novel compounds where propionate pathways are relevant.
• Food & Agricultural Research: Used to investigate preservative efficacy, fermentation processes, and the metabolic fate of propionates in food systems.
• Clinical Diagnostics: Facilitates the accurate measurement of propionate and other short-chain fatty acids in clinical samples for diagnostic purposes.
