Used primarily in research settings as a reference standard for lipid profiling and metabolic studies. It serves as a marker fatty acid in gas chromatography analysis to identify and quantify unsaturated fatty acids in biological samples. Commonly found in studies related to lipid metabolism, particularly in marine oils and human tissue samples, it helps in understanding the biosynthesis and degradation pathways of polyunsaturated fatty acids. Also utilized in the development and validation of analytical methods for food science and clinical diagnostics where accurate identification of cis-configuration fatty acid isomers is critical.
