PackingGroup  III
Safety Profile
Poison by ingestion, skin contact, intraperitoneal, and subcutaneous routes. Experimental teratogenic and reproductive effects. Questionable carcinogen with experimental carcinogenic data. Animal experiments suggest cholinesterase inlubition, possibly due to metabolic products of this material in the body. When heated to decomposition it emits very toxic fumes of NOx and POx.
Toxicity
LD50 in male, female rats (mg/kg): 136, 213 orally (Gaines)
