Safety

Experimental poison by intracerebral route. Moderately toxic to humans by intravenous route. Moderately toxic experimentally by ingestion, subcutaneous, intraperitoneal, and intravenous routes. Human systemic effects by intravenous route: nausea or vomiting and fatty liver degeneration. Experimental reproductive effects. When heated to decomposition it emits very toxic fumes of NO_x and SO_x.
