YELLOW TO BROWN CRYSTALLINE POWDER
The Uses of Phenazine
Phenazine (cas# 92-82-0) is a compound useful in organic synthesis.
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.]
