Chemical Information
FooDB NamePhenoxyacetic acid
DescriptionPhenoxyacetic acid, also known as phenoxyacetate or phenoxyessigsaeure, belongs to the class of organic compounds known as phenoxyacetic acid derivatives. Phenoxyacetic acid derivatives are compounds containing an anisole where the methane group is linked to an acetic acid or a derivative. Phenoxyacetic acid is an extremely weak basic (essentially neutral) compound (based on its pKa). Phenoxyacetic acid is a sweet and sour tasting compound. Phenoxyacetic acid has been detected, but not quantified in, cocoa and cocoa products. This could make phenoxyacetic acid a potential biomarker for the consumption of these foods.
