Hazard Information	Back Directory
[Chemical Properties] Amber liquid; amine odor. Miscible with water and organic solvents.
[Uses] Chemosterilant; in creaseproofing and flameproofing textiles.
[Hazard] Toxic by ingestion and skin absorption, strong irritant to skin.
[Definition] ChEBI: Tris(2-methyl-1-aziridinyl)phosphine oxide is a phosphoramide.
[Production Methods] Metepa was produced commercially through the synthesis of tris(2 methyl 1 aziridinyl)phosphine oxide, an organophosphorus compound. Industrial manufacture involved reacting phosphorus oxychloride with 2 methylaziridine under controlled conditions, allowing three aziridine groups to attach to the phosphorus centre. The process required strict regulation of temperature and solvent environment to prevent polymerisation or hazardous by products, as metepa is highly reactive and toxic.
[Mechanism of action] Causes reproductive sterility in the pest
[Pesticide Type] Insecticide

[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)
