| Safety Data | Back Directory | [TSCA ]
Yes | [Safety Profile]
Mildly toxic by ingestion. An experimental teratogen. When heated to decomposition it emits toxic fumes of NOx. |
| Hazard Information | Back Directory | [Hazard]
It evolves highly toxic fumes on heating to
red heat, but the compound itself has low toxicity.
| [Production Methods]
Potassium ferrocyanide is used as a chemical reagent, in
metallurgy, and in graphic arts. | [Flammability and Explosibility]
