(±)9-HpODE is widely used in biochemical research to study oxidative stress and lipid peroxidation processes. It serves as a key marker for understanding the mechanisms of cellular damage caused by reactive oxygen species. Researchers utilize it to investigate the role of lipid oxidation in various diseases, including atherosclerosis, neurodegenerative disorders, and cancer. Additionally, it is employed in the development of antioxidant therapies and in evaluating the efficacy of compounds that mitigate oxidative damage. Its application extends to studying plant biology, where it helps in understanding the response of plants to environmental stressors.
