Description

2,2,7-Trimethyl-2H,6H,9H,10H-pyrano[2,3-b]carbazole-6,9-dione belongs to the class of organic compounds known as carbazoles. Carbazoles are compounds containing a three ring system containing a pyrrole ring fused on either side to a benzene ring. Pyrayaquinone A is found in Murraya euchrestifolia. 2,2,7-Trimethyl-2H,6H,9H,10H-pyrano[2,3-b]carbazole-6,9-dione is an extremely weak basic (essentially neutral) compound (based on its pKa).
