Chemical Information
NameQuercetin 3'-sulfate
DescriptionQuercetin 3'-sulfate belongs to the class of organic 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. Quercetin 3'-sulfate is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
