Metabolite Identification
Common Name7-Methoxy-6-methyl-2H-1-benzopyran-2-one
Description7-Methoxy-6-methyl-2H-1-benzopyran-2-one belongs to the class of organic compounds known as coumarins and derivatives. These are polycyclic aromatic compounds containing a 1-benzopyran moiety with a ketone group at the C2 carbon atom (1-benzopyran-2-one). 7-Methoxy-6-methyl-2H-1-benzopyran-2-one has been detected, but not quantified in, herbs and spices. This could make 7-methoxy-6-methyl-2H-1-benzopyran-2-one a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 7-Methoxy-6-methyl-2H-1-benzopyran-2-one.
