Phenazine Usage And Synthesis

Chemical Properties

YELLOW TO BROWN CRYSTALLINE POWDER

Definition

ChEBI: An azaarene that is anthracene in which the carbon atoms at positions 9 and 10 are replaced by nitrogen atoms.

Safety Profile

Poison by intraperitoneal and intravenous routes. Questionable carcinogen with experimental tumorigenic data. When heated to decomposition it emits toxic fumes of NOx.

Purification Methods

Phenazine crystallises from EtOH, CHCl3 or ethyl acetate, after pre-treatment with activated charcoal. It can be sublimed in vacuo and purified by zone refining. [Beilstein 23/8 V 389.]
