Description

Arachidic Acid-1-13C is a stable isotope-labeled analog of arachidic acid, a saturated fatty acid, where the carbon-13 isotope is incorporated at the C-1 position. This precise labeling is critical for advanced analytical and research applications, providing a reliable internal standard for mass spectrometry and enabling detailed metabolic pathway studies. It is an essential tool for researchers and quality control laboratories in the pharmaceutical, nutritional science, and biochemistry sectors requiring high-purity isotopic tracers.

Application

• Internal standard for the quantitative analysis of fatty acids and lipids via Gas Chromatography-Mass Spectrometry (GC-MS) and Liquid Chromatography-Mass Spectrometry (LC-MS).
• Tracer compound in metabolic studies and biochemical research to investigate lipid metabolism and biosynthesis pathways.
• Critical reagent in the development and validation of analytical methods for food, nutritional supplement, and pharmaceutical quality control.
• Used in clinical research for studying disorders related to fatty acid metabolism.
• Component in the synthesis of isotopically labeled complex lipids, surfactants, and other derivatives for research purposes.
• Reference material for calibrating analytical instruments and ensuring accuracy in isotopic abundance measurements.
