This methyl ester of the 9 (E),11 (E) -conjugated linoleic acid isomer is a research standard used as a marker for detecting thermally degraded or adulterated cooking oils, particularly in olive oil authentication. It is applied in analytical food chemistry and lipid oxidation studies, both in vitro and in biomarker research.
