Description
TRALOMETHRIN is an orange-to-yellow resinous solid that is a technical-grade insecticide with a concentration of more than 39%.
Uses
Used in Agriculture:
TRALOMETHRIN is used as an insecticide for controlling a range of insects, especially Lepidoptera, in various crops such as cereals, coffee, cotton, fruit, maize, oilseed rape, rice, tobacco, and vegetables.
Used in Wood Protection:
TRALOMETHRIN is used as a wood preservative to protect wood from insect infestation and damage.
Used in Household Applications:
TRALOMETHRIN is used as an insecticide for household use to control insects and pests.
Used in Public Health:
TRALOMETHRIN is used in public health for controlling insects that transmit diseases.
Used in Stored Grains:
TRALOMETHRIN is used for protecting stored grains from insect infestation.
Used in Ectoparasite Control on Animals:
TRALOMETHRIN is used for controlling ectoparasites on animals, such as ticks and mites.

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.
