Flavanonols are compounds containing a flavan-3-one moiety, with a structure characterized by a 2-phenyl-3,4-dihydro-2H-1-benzopyran bearing a hydroxyl group and a ketone at the carbon C2 and C3, respectively (2r,3r)-3,4',7-trihydroxyflavanone is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). (2r,3r)-3,4',7-trihydroxyflavanone can be found in chickpea, common bean, and lima bean, which makes (2r,3r)-3,4',7-trihydroxyflavanone a potential biomarker for the consumption of these food products. 2,3-Dihydro-3,7-dihydroxy-2-(4-hydroxyphenyl)-4H-1-benzopyran-4-one, 9CI 4',7-Dihydroxydihydroflavanol Garbanzol C15H12O5 272.2528 272.068473494 3,7-dihydroxy-2-(4-hydroxyphenyl)-3,4-dihydro-2H-1-benzopyran-4-one 3,7-dihydroxy-2-(4-hydroxyphenyl)-2,3-dihydro-1-benzopyran-4-one 1226-22-8 OC1C(OC2=CC(O)=CC=C2C1=O)C1=CC=C(O)C=C1 InChI=1S/C15H12O5/c16-9-3-1-8(2-4-9)15-14(19)13(18)11-6-5-10(17)7-12(11)20-15/h1-7,14-17,19H VRTGGIJPIYOHGT-UHFFFAOYSA-N belongs to the class of organic compounds known as flavanonols.
