Metabolite Identification
Common NameEthylparaben
DescriptionEthylparaben, also known as e-214 or aseptin a, belongs to the class of organic compounds known as p-hydroxybenzoic acid alkyl esters. These are aromatic compounds containing a benzoic acid, which is esterified with an alkyl group and para-substituted with a hydroxyl group. It is used as an antifungal preservative. Sodium ethyl para-hydroxybenzoate, the sodium salt of ethylparaben, has the same uses and is given the E number E215. Ethylparaben is a drug. Its formula is HO-C6H4-CO-O-CH2CH3. Ethylparaben is a mild and phenolic tasting compound. ethylparaben has been detected, but not quantified, in alcoholic beverages. This could make ethylparaben a potential biomarker for the consumption of these foods. Ethylparaben (ethyl para-hydroxybenzoate) is the ethyl ester of p-hydroxybenzoic acid. Ethylparaben is a potentially toxic compound. As a food additive, it has E number E214.
