Description2-(3,4-dihydroxyphenyl)-3,5-dihydroxy-7-methoxy-4h-chromen-4-one, also known as 7-methoxyquercetin or quercetin 7-methyl ether, is a member of the class of compounds known as flavonols. Flavonols are compounds that contain a flavone (2-phenyl-1-benzopyran-4-one) backbone carrying a hydroxyl group at the 3-position. Thus, 2-(3,4-dihydroxyphenyl)-3,5-dihydroxy-7-methoxy-4h-chromen-4-one is considered to be a flavonoid lipid molecule. 2-(3,4-dihydroxyphenyl)-3,5-dihydroxy-7-methoxy-4h-chromen-4-one is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). 2-(3,4-dihydroxyphenyl)-3,5-dihydroxy-7-methoxy-4h-chromen-4-one can be found in a number of food items such as tea, apple, sweet orange, and parsley, which makes 2-(3,4-dihydroxyphenyl)-3,5-dihydroxy-7-methoxy-4h-chromen-4-one a potential biomarker for the consumption of these food products.
