Application
Isovaleraldehyde was used as standard to evaluate the quality of olive oils by headspace solid-phase microextraction-gas chromatography using flame ionization detection and multivariate analysis. It was used as internal standard in determination of wine aroma carbonyl compounds with 5-8 carbon atoms.
