7-Hydroxy-2-methyl-4-oxo-4H-1-benzopyran-5-acetic acid

Description

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