LEPTOMYCIN B Chemical Properties,Uses,Production
Chemical Properties
Leptophos is a tan, waxy solid
Uses
Insecticide.
General Description
White crystalline or colorless amorphous solid, the technical product is a light tan powder. Used as an insecticide; its use is not permitted in the U.S.
Reactivity Profile
Organophosphates, such as LEPTOMYCIN B, 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.
Health Hazard
LEPTOMYCIN B is highly toxic; it is capable of causing death or permanent injury by exposure during normal use.
Fire Hazard
(Non-Specific -- Organophosphorus Pesticide, n.o.s.) Container may explode in heat of fire. Fire may produce irritating or poisonous gases. Decomposes above 356F. Avoid strong alkalies.
Potential Exposure
A potential danger to those involved in the manufacture, formulation and application of this insecticide. Its use is not currently permitted in the United States of America
Shipping
UN2783 Organophosphorus pesticides, solid, toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials. UN3464 Organophosphorus compound, solid, toxic, n.o.s, Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required
Incompatibilities
Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, and epoxides. Organophosphates are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides and active metals. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.
Waste Disposal
Small amounts may be treated with alkali then burned in a landfill. Large quantities should be incinerated in a unit with effluent gas scrubbing. In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesticidecontainers. Must be disposed properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office
