Common Name

5,6,8-trihydroxy-2-methyl-9-{5,6,8-trihydroxy-2-methyl-4-oxo-2h,3h-naphtho[2,3-b]pyran-9-yl}-2h,3h-naphtho[2,3-b]pyran-4-one

Description

Cephalochromin belongs to the class of organic compounds known as naphthopyranones. Naphthopyranones are compounds containing a naphthopyran skeleton where a ring carbon bears a carboxylic acid group. Naphthtopyran is made up of the pyran ring fused to a naphthalene ring system. 5,6,8-trihydroxy-2-methyl-9-{5,6,8-trihydroxy-2-methyl-4-oxo-2h,3h-naphtho[2,3-b]pyran-9-yl}-2h,3h-naphtho[2,3-b]pyran-4-one is found in Ustilaginoidea virens. Cephalochromin is an extremely weak basic (essentially neutral) compound (based on its pKa).
