[Toxicity]

LD50 in adult male, female rats (mg/kg): 19, 20 orally (Gaines, Linder)
Hazard InformationBack Directory
[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 LEPTOPHOS, 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]

This material is highly toxic; it is capable of causing death or permanent injury by exposure during normal use.
[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
[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.
[First aid]

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Speed in removing material from skin is of extreme importance. Shampoo hair promptly if contaminated. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. Keep victim quiet and maintain normal body temperature. Effects may be delayed; keep victim under observation

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.
[Description]

Leptophos is a tan, waxy solid. Molecularweight 5 412.07; Freezing/Melting point =about 70℃.Hazard Identification (based on NFPA-704 M RatingSystem): Health 3, Flammability 1, Reactivity 0. Practicallyinsoluble in water; solubility = 0.028%.
[Chemical Properties]

Leptophos is a tan, waxy solid
[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
[Uses]

Insecticide.
[Definition]

ChEBI: O-(4-bromo-2,5-dichlorophenyl) O-methyl phenylphosphonothioate is an organic phosphonate that is phenylphosphonothioic O,O-acid in which the hydroxy groups are substituted by methoxy and 4-bromo-2,5-dichlorophenoxy groups. It is a dichlorobenzene, a member of bromobenzenes, an organic phosphonate and a phosphonic ester.
[storage]

Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Prior to working with thischemical you should be trained on its proper handling andstorage. Store in tightly closed containers in a cool, wellventilated area.
