Descrizione generale

Isovaleraldehyde is a short-chain aldehyde that can be produced by oxidizing isoamyl alcohol.

Isovaleraldehyde is an attractant and its interaction with zoospores of the fungus Phytophthora palmivora has been studied by binding techniques.

Applicazioni

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.
