Description

Oleic Acid-D17 CAS NO 223487-44-3 is a deuterium-labeled analog of oleic acid, a monounsaturated ω-9 fatty acid. This stable isotope-labeled compound is essential for use as an internal standard in quantitative mass spectrometry (MS) and nuclear magnetic resonance (NMR) spectroscopy, ensuring precise and accurate analytical measurements. It is a critical tool for researchers and quality control laboratories in the pharmaceutical, nutritional science, and metabolic research sectors, where tracking fatty acid metabolism, profiling lipids, and ensuring product purity are paramount.

Application

• Quantitative Mass Spectrometry (MS) Internal Standard: Used for the accurate quantification of oleic acid and related lipids in complex biological matrices such as plasma, tissues, and cell cultures.
• Metabolic Pathway Tracing: Employed in stable isotope labeling studies to investigate fatty acid metabolism, absorption, and β-oxidation in nutritional and pharmacological research.
• Pharmaceutical Impurity Profiling: Serves as a reference standard in the analysis and quality control of lipid-based drug formulations and active pharmaceutical ingredients (APIs).
• Nutritional Science Research: Facilitates precise measurement of oleic acid content in food products, dietary supplements, and clinical nutrition studies.
• Lipidomics and Biomarker Discovery: A key component in high-throughput lipid profiling workflows for discovering disease biomarkers and understanding lipid-related disorders.
• NMR Spectroscopy Studies: Used as a deuterated probe for structural and dynamic studies of lipids in solution-state NMR.
