Allgemeine Beschreibung

Valeraldehyde also known as pentanal, serves as a precursor or intermediate to build more complex organic molecules.

Anwendung

Valeraldehyde has been used to study its time-weighted average sampling using solid-phase microextraction (SPME) device.
Valeraldehyde is used as a gaseous standard in the study of the sorptive loss pattern for volatile compounds.
Valeraldehyde is used in flavoring compounds and as a rubber accelerator.

In this study, the sorptive loss patterns for volatile organic compounds were evaluated by gaseous standards containing 13 compounds (benzene, toluene, styrene, p-xylene, methyl ethyl ketone, methyl isobutyl ketone, isobutyl alcohol, butyl acetate, acetaldehyde, propionaldehyde, butyraldehyde, isovaleraldehyde, and valeraldehyde). The

A solid-phase microextraction (SPME) device was used as a time-weighted average sampler for n-valeraldehyde. The SPME device was first modified to improve the wearer's acceptance as a passive sampler. Then a poly(dimethylsiloxane)-divinylbenzene fiber was used and O-2,3,4,5,6-(pentafluorobenzyl)hydroxylamine hydrochloride (PFBHA) was
