Description

Oleic-13C18 Acid 99 Atom % 13C CAS NO 312623-86-2 is a high-purity, isotopically labeled form of oleic acid where all 18 carbon atoms are the stable isotope carbon-13. This compound is an essential internal standard and tracer for advanced analytical research, enabling precise quantification and metabolic pathway analysis. It is primarily required by researchers and quality control laboratories in the pharmaceutical, nutritional science, and biochemistry sectors for applications in mass spectrometry (MS), nuclear magnetic resonance (NMR) spectroscopy, and stable isotope probing studies.

Application

• Internal Standard for Quantitative Analysis: Used in Gas Chromatography-Mass Spectrometry (GC-MS) and Liquid Chromatography-Mass Spectrometry (LC-MS) for the accurate quantification of oleic acid and related lipids in complex biological matrices.
• Metabolic Tracer Studies: Enables the tracking of fatty acid metabolism, absorption, and distribution in nutritional, pharmacological, and biochemical research.
• NMR Spectroscopy: Serves as a labeled standard for structural elucidation and dynamic studies due to the distinct NMR signal of carbon-13.
• Pharmaceutical Development: Utilized in drug metabolism and pharmacokinetics (DMPK) studies to trace the fate of lipid-based drug formulations.
• Food Science & Nutrition Research: Applied to study lipid digestion, bioavailability of dietary fats, and the metabolic effects of oleic acid.
• Biomarker Discovery & Validation: Acts as a critical tool in clinical research for developing and validating lipid-based biomarkers in disease states.
• Environmental & Microbial Studies: Used in stable isotope probing (SIP) to investigate microbial communities and their role in lipid degradation.
