2-Ethylbutyric Acid is a flavoring agent that is a clear liquid, color-
less, with a rancid odor. it is miscible in alcohol and ether, sparingly
soluble in water, and is obtained by chemical synthesis.
2-Ethylbutyric acid is used as the internal standard for determining volatile fatty acids (VFAs) in wastewater from the constructed wetlands. It is used in the determination of both free and fatty acids in milk and milk products by HPLC method with direct derivatisation.
By catalytic oxidation of diethylacetaldehyde or by decarboxylation of diethylmalonic acid.
ChEBI: 2-Ethylbutanoic acid is a branched-chain fatty acid.
Taste characteristics at 35 ppm: acidic, fruity, tropical with a creamy aftertaste.
Moderately toxic by
ingestion and skin contact. An irritant to
skin and mucous membranes. A severe eye
irritant. See also ESTERS. Narcotic in high
concentrations. Flammable liquid. To fight
fire, use CO2, dry chemical, alcohol foam.
When heated to decomposition it emits
acrid smoke and fumes.
