Description

Sodium Propionate-1,2-13C2 CAS NO 83587-75-1 is a stable isotope-labeled analog of sodium propionate, a widely used preservative and antifungal agent. This compound is specifically enriched with carbon-13 at the 1 and 2 positions, making it an essential internal standard for precise quantitative analysis via mass spectrometry. It is primarily required by analytical laboratories, pharmaceutical researchers, and food safety testing facilities engaged in advanced metabolic studies, method development, and regulatory compliance testing.

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 biological and food matrices.
• Metabolic Pathway Tracing: Enables the study of propionate metabolism, fatty acid synthesis, and gluconeogenesis in biomedical and nutritional research.
• Pharmaceutical Impurity Profiling: Assists in the identification and quantification of process-related impurities or degradants in drug substances and products containing propionate.
• Food and Feed Safety Analysis: Critical for accurate measurement of propionic acid and its salts in preservative-treated products to ensure compliance with food additive regulations.
• Stable Isotope Dilution Assays (SIDA): Provides high accuracy and precision in analytical methods by correcting for sample preparation and instrumental variability.
• Clinical Diagnostics: Supports research into metabolic disorders such as propionic acidemia by allowing precise tracking of labeled metabolites.

Quality Control

Our Sodium Propionate-1,2-13C2 is manufactured under strict quality systems to ensure exceptional isotopic and chemical purity for research and analytical applications. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing isotopic enrichment (typically >99 atom% 13C), chemical purity (by HPLC/NMR), and other critical parameters. We adhere to relevant standards for high-purity reference materials to guarantee reliable and reproducible performance in your sensitive analytical methods.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure the container is kept tightly sealed in a low-humidity environment to prevent absorption of water and degradation.
