4-hydroxy Nonenal-d3 (Synonyms: 4HNEd3)

4-hydroxy Nonenal-d₃ (4-HNF-d₃) contains three deuterium atoms at the terminal methyl position. It is intended for use as an internal standard for the quantification of 4-HNE by GC- or LC-mass spectrometry. 4-HNE is a lipid peroxidation product derived from oxidized ω-6 polyunsaturated fatty acids such as arachidonic acid.^1,2 4-HNE is widely used as a marker of lipid peroxidation.² It exhibits various biological activities such as cytotoxicity, growth inhibiting activity, genotoxicity, and chemotactic activity.^1,2,3 4-HNE inhibits pro-oxidant-induced Ca²⁺ release from mitochondria at 10-50 µM.²
