| 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 |
| Uses | Leptomycin B is a Streptomyces metabolite that inhibits nuclear export of the human immunodeficiency virus type 1 regulatory protein Rev at low nanomolar concentrations. It covalently binds to cysteine residue in the center of CRM1/exportin 1 protein. |
| 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. |
| 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 involvedin the manufacture, formulation and application of thisinsecticide. Its use is not currently permitted in the UnitedStates of America |
| First aid | If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Speed in removing material from skinis of extreme importance. Shampoo hair promptly if contaminated. Seek medical attention immediately. If thischemical has been inhaled, remove from exposure, beginrescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medical attention. Give large quantities of water and inducevomiting. Do not make an unconscious person vomit. Keepvictim quiet and maintain normal body temperature. Effectsmay be delayed; keep victim under observation.Note to physician: 1,10-trimethylenebis(4-formylpyridiniumbromide)dioxime (a.k.a TMB-4 dibromide and TMV-4) hasbeen used as an antidote for organophosphate poisoning. |
| 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. |
| 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 aresusceptible to formation of highly toxic and flammablephosphine gas in the presence of strong reducing agentssuch as hydrides and active metals. Partial oxidation byoxidizing agents may result in the release of toxic phosphorus oxides. |
| Waste Disposal | Small amounts may be treatedwith alkali then burned in a landfill. Large quantitiesshould 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 federalenvironmental control agency, or by contacting yourregional EPA office |
