Common Name

5,5′-dimethyl-4,4′,7,7′-tetramethoxy-8,8′-bicoumarin

Description

(+)-Kotanin belongs to the class of organic compounds known as coumarins and derivatives. 5,5′-dimethyl-4,4′,7,7′-tetramethoxy-8,8′-bicoumarin was first documented in 1971 (PMID: 5551701). These are polycyclic aromatic compounds containing a 1-benzopyran moiety with a ketone group at the C2 carbon atom (1-benzopyran-2-one) (+)-kotanin is an extremely weak basic (essentially neutral) compound (based on its pKa) (PMID: 17315249).
