Used primarily as a reference standard or internal standard in gas chromatography (GC) and mass spectrometry (MS) for the analysis of fatty acid methyl esters (FAMEs). Commonly employed in biodiesel characterization and lipid profiling due to its well-defined retention time and stability. Also serves as a model compound in studies involving lipid metabolism and in the calibration of analytical instruments for fatty acid analysis. Its straight-chain saturated structure makes it suitable for evaluating chromatographic resolution and detector response in lipid research.
