Common Name

8,8-Dimethyl-2-phenyl-4H,8H-benzo[1,2-b:3,4-b']dipyran-4-one

Description

8,8-Dimethyl-2-phenyl-4H,8H-benzo[1,2-b:3,4-B']dipyran-4-one belongs to the class of organic compounds known as pyranoflavonoids. Pyranoflavonoids are compounds containing a pyran ring fused to a 2-phenyl-1,4-benzopyran skeleton. Thus, 8,8-dimethyl-2-phenyl-4H,8H-benzo[1,2-b:3,4-B']dipyran-4-one is considered to be a flavonoid lipid molecule. 8,8-Dimethyl-2-phenyl-4H,8H-benzo[1,2-b:3,4-b']dipyran-4-one is found in Dahlstedtia pentaphylla, Dahlstedtia pinnata, Lonchocarpus subglaucescens and Millettia pulchra. 8,8-Dimethyl-2-phenyl-4H,8H-benzo[1,2-b:3,4-B']dipyran-4-one is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
