Used primarily in research settings as a reactive aldehyde derived from lipid peroxidation, this compound serves as a model substance for studying oxidative stress in biological systems. It helps investigate the effects of polyunsaturated aldehydes on cell signaling, inflammation, and apoptosis. Due to its structural similarity to lipid oxidation products formed in vivo, it is applied in studies related to aging, neurodegenerative diseases, and cardiovascular disorders. It is also utilized in biochemical assays to evaluate antioxidant efficacy and cellular defense mechanisms against reactive electrophiles.
