Metabolite Identification
Common NameEthoxyacetic acid
DescriptionEthoxyacetic acid, also known as ethoxyacetate, belongs to the class of organic compounds known as carboxylic acids. Carboxylic acids are compounds containing a carboxylic acid group with the formula -C(=O)OH. Ethoxyacetic acid has been detected, but not quantified in, herbs and spices and milk (cow). This could make ethoxyacetic acid a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on Ethoxyacetic acid.
