9-Methoxy-alpha-lapachone

Description

9-Methoxy-alpha-lapachone 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. 9-Methoxy-alpha-lapachone is found in Catalpa ovata and Mansoa alliacea. 9-Methoxy-alpha-lapachone is an extremely weak basic (essentially neutral) compound (based on its pKa).
