The Uses of 2-Ethylbutyric acid

Ester formation; intermediate for drugs, dyestuffs, chemicals; flavoring.

The Uses of 2-Ethylbutyric acid

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.

Preparation

By catalytic oxidation of diethylacetaldehyde or by decarboxylation of diethylmalonic acid.
