10453-86-8 Usage
Chemical Properties
Off-white to tan waxy solid or colorless crys-
tals. Chrysanthemum-like odor. Commercial products may
be dissolved in flammable organic solvents
Uses
Resmethrin is used to control a wide range of insects in horticultural,
household, public health and animal health situations. It has
some agricultural use but this is limited. The more active 1Rtrans form has
a similar range of uses and is also used in stored grain products.
General Description
Colorless crystals or waxy solid. Insoluble in water. Used as an insecticide.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
A pyrethroid derivative.
Agricultural Uses
Insecticide: Resmethrin is currently used for mosquito control (by aerial application) in the USA, and may can also be used in greenhoused to control white fly. Resmethrin is a synthetic Type I pyrethroid insecticide registered for control of insects in residential, commercial and industrial settings, and in animal living areas. Resmethrin is also registered for use in food-handling establishments and as a restricted use pesticide when used in ULV spray to control adult mosquitoes in the interest of public health[83]. Restricted Use Pesticide (RUP) when formulated for use in mosquito abatement and pest control treatments at nonagricultural sites. Restricted due to extreme fish toxicity. Not approved for use in EU countries.

Safety Profile
Poison by ingestion, andintravenous routes. Moderately toxic by inhalation andskin contact. When heated to decomposition it emits acridand irritating fumes.

(RUP) when formulated for use in mosquito abatement and
pest control treatments at nonagricultural sites. Restricted
due to extreme fish toxicity.
Metabolic pathway
14C-resmethrin are
individually administered orally to white leghorn hens,
and more than 90% of the radioactivity is eliminated in
the excreta within 24 h of treatment. The metabolic
routes for both resmethrin isomers arise from ester
hydrolysis and oxidation of the hydrolytic products.
Some of these metabolites are further conjugated with
glucuronic acid, sulfate, or other unidentified
compounds before excretion.

Degradation
The resmethrins are reasonably stable but they are sensitive to base
hydrolysis forming the chrysanthemic acid isomers (2) and 5-benzyl-3-
furylmethanol (3). They are also sensitive to oxidation and to photodecomposition.
Photo-oxidation involves degradation of the furan ring
to yield a cyclic ozonide peroxide by addition of oxygen across the unsaturated
system forming the hydroxylactone derivative (4), the benzyloxylactone
derivative (5) and the hydroxycyclopentenolone (6) (Ueda
et al., 1974). These chemical and photochemical reactions are shown in
Scheme 1.Degradation also occurs in the acid moiety by reactions analogous to
those described under phenothrin, for example, oxidation at the isobutylene
substituent to afford a variety of alcohols, aldehydes and carboxylic acids. These two sites of weakness in the resmethrin molecule result
in considerable photo-instability (though they are more stable than the
pyrethrins) and to a complex mixture of degradation products.
Incompatibilities
Decomposed by air, light, alkaline
media, and temperatures .175℃. May react violently with
strong oxidizers, bromine, 90% hydrogen peroxide, phos-
phorus trichloride, silver powders or dust. Incompatible
with silver compounds. Mixture with some silver
compounds forms explosive salts of silver oxalate.
Waste Disposal
Incineration would be an
effective disposal procedure where permitted. If an efficient
incinerator is not available, the product should be mixed with large amounts of combustible material and contact
with the smoke should be avoided. In accordance with
40CFR165. Follow recommendations for the disposal of
pesticides and pesticide containers . Bury in noncrop
land away from water. It would be better to mix the prod-
uct with lime. Incineration would be an effective disposal
procedure where permitted. If an efficient incinerator is not
available, the product should be mixed with large amount
of combustible material. Recommendable methods:
Hydrolysis, landfill, incineration, and open burning. Not
recommendable method: Discharge to sewer. Mix with saw-
dust and burn at a remote place .
Check Digit Verification of cas no
The CAS Registry Mumber 10453-86-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,4,5 and 3 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 10453-86:
(7*1)+(6*0)+(5*4)+(4*5)+(3*3)+(2*8)+(1*6)=78
78 % 10 = 8
So 10453-86-8 is a valid CAS Registry Number.
