Used primarily in research settings as a model compound for studying the behavior of oxidized lipids in biological systems. It serves as a marker for lipid peroxidation, helping scientists understand oxidative stress in cell membranes. Due to its structural similarity to naturally occurring oxidized cholesterol esters, it is employed in studies related to atherosclerosis and foam cell formation. Also utilized in analytical chemistry as a reference standard in mass spectrometry and chromatography to identify and quantify oxidized lipids in complex biological samples.
