General description
Acetaldehyde comprises of a carbonyl group linked to a hydrogen atom. It is a well-known mutagen and carcinogen.
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).
It may be used as a reference standard for the detection of acetaldehyde which is formed as a pyrolysis product of tobacco additives and as endogenous aldehyde in human urine by gas chromatography-mass spectrometry technique.
