Used primarily as a reference standard or internal standard in gas chromatography and mass spectrometry for the analysis of fatty acid methyl esters (FAMEs). Its long-chain structure makes it suitable for calibrating instruments in lipid profiling and biodiesel research. Also found in trace amounts in some natural oils, where it may serve as a biomarker in metabolic and environmental studies. Due to its stability and hydrophobic nature, it can be used in cosmetic formulations as an emollient or skin-conditioning agent. Additionally, it has applications in the study of wax esters and cuticular lipids in plants and insects.
