Metabolite Identification
Common Name3-Hydroxy-2H-pyran-2-one
Description3-Hydroxy-2H-pyran-2-one belongs to the class of organic compounds known as pyranones and derivatives. Pyranones and derivatives are compounds containing a pyran ring which bears a ketone. 3-Hydroxy-2H-pyran-2-one has been detected, but not quantified in, alcoholic beverages. This could make 3-hydroxy-2H-pyran-2-one a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 3-Hydroxy-2H-pyran-2-one.
