Safety Profile
Moderately toxic by ingestion. Questionable carcinogen with experimental tumorigenic data. An eye irritant. Irritating to abraided skin. Violent reaction with ETHANOL. Reacts with CHLORINE to form a spontaneously explosive product. When heated to decomposition it emits very toxic fumes of NOx and CN?. Used to stabilize CHLORINE solutions used in swimming pools.
