PHOSFOLAN Specification

1.General Description: Colorless to yellow solid. Used as an insecticide.
2.Air & Water Reactions :Hydrolyzed by alkalis. 
3.Reactivity Profile :Organophosphates, such as  Phosfolan (CAS NO.947-02-4) , are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.
4.Health Hazard :Similar to parathion. Death may result due to respiratory arrest as a result of paralysis of respiratory muscles and intense bronchoconstriction. Also considered a cholinesterase inhibitor.
5.Fire Hazard :(Non-Specific -- Organophosphorus Pesticide, n.o.s.) Phosfolan  may burn but does not ignite readily. Container may explode in heat of fire. When heated to decomposition, Phosfolan (CAS NO.947-02-4) emits very toxic fumes of oxides of phosphorus, sulfur, and nitrogen. Hydrolyzed by alkalies.
