4Hydroxynonanal

4Hydroxynonanal is a chemical compound with the molecular formula C9H18O2. It is a hydroxyl aldehyde, meaning it contains both a hydroxyl (-OH) functional group and an aldehyde (-CHO) functional group. The "4-hydroxy" designation indicates that the hydroxyl group is attached to the fourth carbon atom of the nonanal chain. Nonanal itself is a nine-carbon straight-chain aldehyde.

This compound can be synthesized through various organic reactions, often involving oxidation or reduction steps. Its properties, such as boiling point and solubility, are influenced by the presence of both the polar hydroxyl and aldehyde groups. 4Hydroxynonanal can participate in reactions characteristic of both alcohols and aldehydes, including oxidation, reduction, and nucleophilic addition.

In biological contexts, 4hydroxynonanal has been identified as a marker or product of lipid peroxidation. Specifically, it is formed from the oxidative degradation of linoleic acid and its derivatives. Elevated levels of 4hydroxynonanal in biological samples are sometimes associated with oxidative stress and can be relevant in the study of certain physiological and pathological conditions. Its presence can be detected and quantified using analytical techniques like gas chromatography-mass spectrometry.
