7-Hydroxy-2,5-dimethyl-4H-1-benzopyran-4-one

Description

7-Hydroxy-2,5-dimethyl-4H-1-benzopyran-4-one belongs to the class of organic compounds known as chromones. Chromones are compounds containing a benzopyran-4-one moiety. 7-Hydroxy-2,5-dimethyl-4H-1-benzopyran-4-one has been detected, but not quantified in, green vegetables. This could make 7-hydroxy-2,5-dimethyl-4H-1-benzopyran-4-one a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 7-Hydroxy-2,5-dimethyl-4H-1-benzopyran-4-one.
