• Effects of Short Term Exposure: The substance is irritating to the eyes and respiratory tract. The substance is mildly irritating to the skin. If swallowed the substance may cause vomiting and could result in aspiration pneumonitis.
• Description: May be prepared by oxidation of isoamyl alcohol.
• Uses: Isovaleraldehyde is manufactured by oxidizing isoamyl alcohol with sodium perchromate and sulfuric acid. Isovaleraldehyde is present in essential oils of orange, peppermint, lemon, and other plants and fruits. Its main uses are as an artificial flavor additive and in perfumes. Isovaleraldehyde acts as a reagent in the preparation of active pharmaceutical ingredient (API) products. It serves as an internal standard for the determination of wine aroma carbonyl compounds with 5-8 carbon atoms. Further, it is utilized as a standard to evaluate the quality of olive oils by headspace solid-phase microextraction-gas chromatography using flame ionization detection and multivariate analysis. In addition to this, it is employed to enhance the taste and odor of the food. In artificial flavors and perfumes.
