66841-25-6 Usage
Description
Orange-to-yellow resinous solid (technical grade
>39%)
Uses
Different sources of media describe the Uses of 66841-25-6 differently. You can refer to the following data:
1. Tralomethrin can be used as insecticide.
2. 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.
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.
Agricultural Uses

for use in the U.S.
Trade name

RU-25474?; SCOUT?; SCOUT? X-TRA Gel insecticide
Metabolic pathway
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.
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.
Toxicity evaluation
Acute oral LD50 for rats: 99-3,000 mg/kg depending on the
carrier used
Check Digit Verification of cas no
The CAS Registry Mumber 66841-25-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,8,4 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 66841-25:
(7*6)+(6*6)+(5*8)+(4*4)+(3*1)+(2*2)+(1*5)=146
146 % 10 = 6
So 66841-25-6 is a valid CAS Registry Number.
