General description

Acetaldehyde comprises of a carbonyl group linked to a hydrogen atom.[1] It is a well-known mutagen and carcinogen.[2]
This substance is listed on the positive list of the EU regulation 10/2011 for plastics intended to come into contact with food. Find all available reference materials for compounds listed in 10/2011 here

Application

Acetaldehyde has been used as a reference standard for the determination of acetaldehyde as a volatile constituent of extra virgin olive oil (EVOO) by gas chromatography coupled with ion mobility spectrometry (IMS).[3]
It may be used as a reference standard for the detection of acetaldehyde which is formed as a pyrolysis product of tobacco additives[4] and as endogenous aldehyde in human urine[5] by gas chromatography-mass spectrometry technique.

Analysis Note

acetaldehyde forms the diacetal in alcoholic solution
