Description

Linoleic Acid-13C18 is a stable isotope-labeled analog of linoleic acid, where all 18 carbon atoms are the carbon-13 (13C) isotope. This compound is an essential tool for precise quantitative analysis and metabolic pathway tracing in advanced research. It is primarily utilized by scientists and quality control professionals in the pharmaceutical, nutritional science, and biomedical research industries who require the highest level of accuracy in their analytical and tracer studies.

Application

• Internal Standard for Mass Spectrometry: Serves as a critical quantitative reference standard in GC-MS and LC-MS analyses for accurate measurement of endogenous linoleic acid levels in biological samples.
• Metabolic Flux Analysis: Used as a tracer to study the metabolism, absorption, and conversion pathways of polyunsaturated fatty acids in vivo and in vitro.
• Pharmaceutical R&D: Enables precise pharmacokinetic and bioavailability studies of lipid-based drug formulations and nutraceuticals.
• Clinical Diagnostics: Supports the development and validation of diagnostic assays for fatty acid-related disorders.
• Nutritional Research: Facilitates detailed investigations into the metabolic fate of dietary lipids and their role in health and disease.
• Isotope Dilution Assays: Provides the foundational component for high-accuracy methods in food science and regulatory testing.

Quality Control

Every batch of Linoleic Acid-13C18 is manufactured and tested under strict quality management systems to ensure exceptional isotopic and chemical purity, critical for research integrity. Our products undergo rigorous quality testing, including advanced spectroscopic and chromatographic methods, to ensure compliance with industry standards for stable isotope-labeled compounds. Certificates of Analysis (COA) detailing isotopic enrichment, chemical purity, and analytical methods are provided with each shipment.

Storage

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