Used as a reference standard in gas chromatography for analyzing fatty acid methyl esters, particularly in studies involving unsaturated fatty acids. It helps identify and quantify similar compounds in biological samples, such as blood, tissues, and oils. Commonly applied in lipidomics and metabolic research to understand fatty acid metabolism and its role in health and disease. Also utilized in the development and testing of functional foods and nutraceuticals where precise fatty acid profiling is required.
