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.

Upon hexanal-modification in the presence of NaCNBH(3), the oxidized B chain of insulin becomes mono- and further dialkylated on both the N-terminal and Lys(29) residues. A pseudo-MS(3) study was performed with a triple-quadrupole mass spectrometer on the different modified lysine-containing

The application of high-amplitude ultrasound to liquids triggers cavitation. By the collapse of the thereby appearing vacuum cavities, high temperatures can be reached in a transient manner. The high temperatures in these hot-spots can lead to homolytic scission of chemical
