Flavones are flavonoids with a structure based on the backbone of 2-phenylchromen-4-one (2-phenyl-1-benzopyran-4-one). Thus, 3',4',7-trihydroxyflavone is considered to be a flavonoid lipid molecule. 3',4',7-Trihydroxyflavone is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). 3',4',7-Trihydroxyflavone can be found in alfalfa, broad bean, and fenugreek, which makes 3',4',7-trihydroxyflavone a potential biomarker for the consumption of these food products. 2-(3,4-Dihydroxyphenyl)-7-hydroxy-4H-1-benzopyran-4-one C15H10O5 270.2369 270.05282343 2-(3,4-dihydroxyphenyl)-7-hydroxy-4H-chromen-4-one 2-(3,4-dihydroxyphenyl)-7-hydroxychromen-4-one 2150-11-0 OC1=CC2=C(C=C1)C(=O)C=C(O2)C1=CC(O)=C(O)C=C1 InChI=1S/C15H10O5/c16-9-2-3-10-12(18)7-14(20-15(10)6-9)8-1-4-11(17)13(19)5-8/h1-7,16-17,19H PVFGJHYLIHMCQD-UHFFFAOYSA-N belongs to the class of organic compounds known as flavones.
