Isovaleraldehyde Usage And Synthesis
May be prepared by oxidation of isoamyl alcohol.
3-Methylbutyraldehyde has a choking, powerful, acrid, pungent, apple-like odor. This compound is also reported to have a fruity, fatty, animal, almond odor.
colourless liquid with a strong and (for some
Isovaleraldehyde is a colorless, low-solubility liquid with a pungent odor similar to that of apples.

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.
ChEBI: A methylbutanal that is butanal substituted by a methyl group at position 3. It occurs as a volatile constituent in olives.
By oxidation of isoamyl alcohol.
Colorless liquid with a weak suffocating odor. Floats on water. Produces an irritating vapor.
Air & Water Reactions
Isovaleraldehyde is an aldehyde. Aldehydes are frequently involved in self-condensation or polymerization reactions. These reactions are exothermic; they are often catalyzed by acid. Aldehydes are readily oxidized to give carboxylic acids. Flammable and/or toxic gases are generated by the combination of aldehydes with azo, diazo compounds, dithiocarbamates, nitrides, and strong reducing agents. Aldehydes can react with air to give first peroxo acids, and ultimately carboxylic acids. These autoxidation reactions are activated by light, catalyzed by salts of transition metals, and are autocatalytic (catalyzed by the products of the reaction). The addition of stabilizers (antioxidants) to shipments of aldehydes retards autoxidation.
Inhalation causes chest discomfort, nausea, vomiting, and headache. Contact of liquid with eyes or skin causes irritation. Ingestion causes irritation of mouth and stomach.
