Metabolite Identification

Common Name

2'-Hydroxy-5'-methylacetophenone

Description

2'-Hydroxy-5'-methylacetophenone 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'-Hydroxy-5'-methylacetophenone is a sweet, floral, and heavy tasting compound. 2'-Hydroxy-5'-methylacetophenone has been detected, but not quantified in, a few different foods, such as arabica coffees (Coffea arabica), coffee and coffee products, and robusta coffees (Coffea canephora). This could make 2'-hydroxy-5'-methylacetophenone a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on 2'-Hydroxy-5'-methylacetophenone.
