Definition
ChEBI: Tris(2-methyl-1-aziridinyl)phosphine oxide is a phosphoramide.
Hazard
Toxic by ingestion and skin absorption, strong irritant to skin.
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.
