TRALOMETHRIN Chemische Eigenschaften,Einsatz,Produktion Methoden

Beschreibung
Orange-to-yellow resinous solid (technical grade >39%)
Verwenden
Tralomethrin controls a range of insects, especially Lepidoptera, in cereals, coffee, cotton, fruit, maize, oilseed rape, rice, tobacco and vegetables. It is also effective for wood protection, household use, in public health, in stored grains and for ectoparasite control on animals.
Verwenden
Tralomethrin can be used as insecticide.
Definition
ChEBI: A carboxylic ester resulting from the formal condensation between (1R)-cis-2,2-dimethyl-3-(1,2,2,2-tetrabromoethyl)cyclopropanecarboxylic acid and the alcoholic hydroxy group of (2S)-hydroxy(3-phenoxypheny )acetonitrile.
Landwirtschaftliche Anwendung
Insecticide: Not approved for use in EU countries. Registered for use in the U.S.
Handelsname
DETHMOR®; HAG-107®; RU-25472®; RU-25474®; SCOUT®; SCOUT® X-TRA Gel insecticide
Stoffwechselwegen
Tralomethrin probably owes most of its action to rapid conversion by several mechanisms to deltamethrin. Information on its photodegradation, degradation in soil, and its metabolism in plants, insects and animals has been published and supports this conclusion.
Toxicity evaluation
Acute oral LD₅₀ for rats: 99-3,000 mg/kg depending on the carrier used
Degradation
Tralomethrin is stable as a solid but is labile to base. Acidic media reduce the tendency to hydrolysis and epimerisation. It was readily debrominated when solutions or thin films were irradiated at 360 nm or by sunlight. Homolytic fission of a C-Br bond initiates this reaction, which affords deltamethrin (2). Some epimerisation to trans-tralomethrin and thence trans-deltamethrin also occurred. Dehydrobromination also affords deltamethrin and the tribromo derivative (8). Ester cleavage to the acid (3) and to the cyanohydrin (5) and thence to 3PBAl (6) and 3PBA (7) is important in the solid phase but not in solution (Ruzo and Casida, 1981). The products are shown in Scheme 1.
