63333-35-7 Usage
Chemical Properties
Pale yellow, water-insoluble crystalline
substance.
Uses
Different sources of media describe the Uses of 63333-35-7 differently. You can refer to the following data:
1. Bromethalin is used to control rats and mice indoors and outdoors.
It is more effective against rats.
2. Rodenticide.
Hazard
Poisonous; moderately toxic; causes
headache, confusion, personality changes, seizures,
coma, death.
Metabolic pathway
Bromethalin is a complex molecule possessing several functional groups
and rapid and multi-pathway metabolism would be expected. There is a
dearth of information published on its environmental fate and metabolism
in plants but some limited information on metabolism in rats is
available.
Degradation
Bromethalin is stable under normal storage conditions but it is degraded
by UV light.
Toxicity evaluation
Bromethalin is produced by reaction of 2,4-dinitro-6-
trifluoromethyl methylaniline with 1,2,3,5-tetrabromobenzene
(15).
This compound has been known for some time to have
rodenticidal properties (16) but has only recently been
made available. Bromethalin is used in baits at a concentration
of 0.005 or 0.01% and is effective against rodents
resistant to anticoagulants. It does not induce bait shyness.
Anorexia occurs after an effective dose has been consumed.
The mode of action is by uncoupling oxidative phosphorylation
in cells of the central nervous system. Symptoms
of poisoning include tremors, convulsions, prostration, and
hind-limb paralysis. No specific antidote is available but a
symptomatic treatment has been described (17).
Trade Names. Assault (Purina Mills), Vengeance (Dow-
Elanco).
The following acute and subacute compounds are used
for rodent control less frequently than those listed above,
either because they are not widely available or because
restrictions have been placed upon their use due to safety
considerations (11,18).
Check Digit Verification of cas no
The CAS Registry Mumber 63333-35-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,3,3 and 3 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 63333-35:
(7*6)+(6*3)+(5*3)+(4*3)+(3*3)+(2*3)+(1*5)=107
107 % 10 = 7
So 63333-35-7 is a valid CAS Registry Number.

N-Alkyldiphenylamines
-
, (2008/06/13)
A series of new diphenylamines have small alkyl substituents on the amino nitrogen and are useful as intermediates for the preparation of rodenticidal diphenylamines. One phenyl ring has 2,4-dinitro-6-trifluoromethyl substitution, and the other is substituted with no more than one methyl or trifluoromethyl group. The invention is particularly directed to N-alkyl-2,4-dinitro-3'-6-bis(trifluoromethyl)diphenylamines, which are additionally useful as insecticides and arachnicides.
