Triphendioxazine is a heterocyclic compound in which five six-membered rings are fused linearly. The eponymous basic building block is 2 H -1,4-oxazine. Two such 2 H -1,4-oxazines are [1,2- b : 4,5- b ' ] fused to a benzene ring to give benzo [1,2- b : 4,5- b' ] to [1,4 ] oxazine. The annulation of two further benzene rings yields [1,4] benzoxazino [2,3- b ] phenoxazine, which is shortened, but chemically imprecise, also called dioxazine . (Not to be confused with dioxin .)
