Description

Sodium Propionate-2,3-13C2, 99 Atom % 13 C is a high-purity, stable isotope-labeled derivative of sodium propionate, a common food preservative and antifungal agent. This compound is specifically enriched with carbon-13 at the 2 and 3 positions, making it an invaluable internal standard and tracer for advanced analytical and metabolic research. It is essential for scientists and quality control laboratories requiring precise quantification and pathway analysis. Primary users include pharmaceutical R&D teams, academic research institutions, and manufacturers in the food science and agricultural chemistry sectors.

Application

• Quantitative Analytical Standard: Used as an internal standard in Liquid Chromatography-Mass Spectrometry (LC-MS) and Gas Chromatography-Mass Spectrometry (GC-MS) for the accurate quantification of propionate and related compounds in complex matrices.
• Metabolic Pathway Tracing: Employed in 13C-NMR spectroscopy and isotope-ratio mass spectrometry studies to elucidate metabolic fluxes and biochemical pathways in microbial, plant, and mammalian systems.
• Pharmaceutical Development: Serves as a labeled precursor or reference material in the research and development of new drugs, particularly those involving propionate metabolism or antifungal mechanisms.
• Food Safety & Quality Assurance: Acts as a certified reference material for validating analytical methods used to monitor propionate preservative levels in food and beverage products to ensure regulatory compliance.
• Environmental & Agricultural Research: Applied in studies investigating the environmental fate of propionates, soil microbiology, and the metabolism of fungicides in crops.
• Clinical Diagnostics: Utilized in developing advanced diagnostic assays for inborn errors of metabolism, such as propionic acidemia, where precise measurement of propionate is critical.
