General description

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

Application

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.
