Description

Oleic Acid-1-13C is a stable isotope-labeled analog of oleic acid, a monounsaturated ω-9 fatty acid, where the carbon at the 1-position is enriched with the 13C isotope. This precise labeling makes it an indispensable tool for advanced metabolic and biochemical research, enabling accurate tracing and quantification in complex biological systems. It is primarily required by researchers and manufacturers in the pharmaceutical, nutritional science, and analytical chemistry sectors for use as an internal standard in mass spectrometry, NMR spectroscopy, and metabolic flux studies.

Application

• Internal Standard for Mass Spectrometry (MS): Used for the precise quantification of oleic acid and its metabolites in biological samples via GC-MS or LC-MS.
• Metabolic Pathway Tracing: Enables the study of fatty acid metabolism, β-oxidation, and lipid biosynthesis in cell cultures, tissues, and whole organisms.
• NMR Spectroscopy Studies: Serves as a probe for structural and dynamic studies of lipids and membranes due to the distinct 13C NMR signal.
• Pharmaceutical Research: Utilized in drug development to investigate the pharmacokinetics and metabolic fate of lipid-based therapeutics.
• Nutritional Science: Applied in research on dietary fat absorption, metabolism, and their impact on health and disease.
• Biochemical Assay Development: Acts as a critical component in developing and validating assays for clinical diagnostics and research.
• Isotope Dilution Analysis: Provides high accuracy and precision in the measurement of oleic acid concentrations in complex matrices like food, supplements, and bodily fluids.

Quality Control

Our Oleic Acid-1-13C is produced and handled under strict quality protocols to ensure isotopic and chemical purity for critical research applications. Each batch is characterized by advanced analytical techniques including NMR, GC-MS, and HPLC to confirm isotopic enrichment, chemical identity, and purity. Certificates of Analysis (COA) detailing isotopic purity (atom % 13C), chemical purity, and analytical results are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C under an inert atmosphere (e.g., nitrogen or argon) to minimize oxidation. For long-term storage, keep the sealed container in a freezer at or below -20°C. Allow the product to reach room temperature in the sealed container before opening to prevent condensation and moisture ingress.
