Metabolite Identification
Common Name2',4'-Dimethylacetophenone
Description2',4'-Dimethylacetophenone belongs to the class of organic compounds known as alkyl-phenylketones. These are aromatic compounds containing a ketone substituted by one alkyl group, and a phenyl group. 2',4'-Dimethylacetophenone is a sweet, floral, and mimosa tasting compound. 2',4'-Dimethylacetophenone has been detected, but not quantified in, several different foods, such as black tea, green tea, herbal tea, red tea, and teas (Camellia sinensis). This could make 2',4'-dimethylacetophenone a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 2',4'-Dimethylacetophenone.
