Description
Cyfluthrin is a broad-spectrum synthetic pyrethroid insecticide with both contact and poison action. It is a modulator of voltage-gated sodium channels (Nav) and is known for its neurotoxic properties. Cyfluthrin is highly toxic to fish, aquatic organisms, and bees.
Used in Agriculture:
Cyfluthrin is used as an insecticide for controlling a wide range of pests in various crops, including cereals, fruits, vegetables, and cotton. It targets pests such as cutworms, ants, silverfish, cockroaches, termites, grain beetles, weevils, mosquitoes, fleas, flies, corn earworms, tobacco budworm, codling moth, European corn borer, cabbageworm, loopers, armyworms, boll weevil, alfalfa weevil, Colorado potato beetle, and many others.
Used in Public Health:
Cyfluthrin is used in public health situations to control insects that pose health risks to humans, such as mosquitoes and flies.
Used in Structural Pest Control:
Cyfluthrin is used for controlling insects in and around homes, food handling establishments, and other structures, including ants, silverfish, cockroaches, and termites.
Used in Stored Products:
Cyfluthrin is used to protect stored products from insect infestations, such as grain beetles and weevils.
Used in Animal Health:
Cyfluthrin is used to control insects that may affect the health and well-being of animals, such as migratory locusts and grasshoppers.

Potential Exposure
Cyfluthrin is a synthetic pyrethroid,
nonsystemic insecticide used to control a variety of chew-
ing and sucking insects on cotton, hops, cereals, corn, pea-
nuts, fruit, potatoes, and other crops and vegetables. It is
also used to control structural pests such as termites.
Cyfluthrin can be found in both Restricted Use Pesticides
(RUP) and General Use Pesticides (GUP) category. It is
also a nitrile.
Metabolic pathway
The non-enzymatic hydrolyzed products of 14C-
cyfluthrin are isolated and identified by the incubation
reaction mixture of a buffer solution. The products are
derived from the hydrolysis of the ester linkage of
cyfluthrin via cyanhydrin. This results in the
corresponding aldehyde which undergoes both
oxidation and reduction to give rise to carboxylic acid
and benzyl alcohol, respectively.

Degradation
Cyfluthrin is a stable compound but it is hydrolysed at high pH. DT50
values in water at 22 °C at pH 4, 7 and 9 were 25-117, 11-20, and 3-7
days, respectively (PM). Under aqueous photolysis conditions (but using
UV light and acetonitrile in the solution), its half-life was 12 days. The
benzldehyde (3, 3%) (Scheme 1) and the benzoic acid (5, 9%) were
detected at 144 hours (PSD).
On a soil surface in light, the initial half-life was 2 days. At day 9, 62%
of the radioactivity was recovered as: cyfluthrin (36%)) 3 (2%), 5 (4%)
and unidentified components (PSD). The compound was stable on a soil
surface in the dark.
Incompatibilities
May react violently with strong oxidi-
zers, bromine, 90% hydrogen peroxide, phosphorus
trichloride, silver powders, or dust. Incompatible with silver
compounds. Mixture with some silver compounds forms
explosive salts of silver oxalate. Nitriles may polymerize in
the presence of metals and some metal compounds. They
are incompatible with acids; mixing nitriles with strong
oxidizing acids can lead to extremely violent reactions.
Nitriles are generally incompatible with other oxidizing
agents such as peroxides and epoxides. The combination of
bases and nitriles can produce hydrogen cyanide. Nitriles
are hydrolyzed in both aqueous acid and base to give car-
boxylic acids (or salts of carboxylic acids). These reactions
generate heat. Peroxides convert nitriles to amides. Nitriles
can react vigorously with reducing agents. Acetonitrile and
propionitrile are soluble in water, but nitriles higher than
propionitrile have low aqueous solubility. They are also
insoluble in aqueous acids
.
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.
Check Digit Verification of cas no
The CAS Registry Mumber 68359-37-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,3,5 and 9 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 68359-37:
(7*6)+(6*8)+(5*3)+(4*5)+(3*9)+(2*3)+(1*7)=165
165 % 10 = 5
So 68359-37-5 is a valid CAS Registry Number.

Chiral stability of synthetic pyrethroid insecticides
Liu, Weiping,Qin, Sujie,Gan, Jianying
, p. 3814 - 3820 (2007/10/03)
Synthetic pyrethroids are chiral compounds consisting of multiple stereoisomers. Evaluation of enantioselectivity in environmental fate and ecotoxicity requires analytical methods that preserve stereoisomer integrity during analysis. In this study, we characterized the stability of stereoisomers from four commonly used pyrethroids, cis-bifenthrin (cis-BF), permethrin (PM), cypermethrin (CP), and cyfluthrin (CF), during gas chromatography (GC) analysis and sample preparation. Stereoisomers of cis-BF and PM were found to be stable, but those of CP and CF were unstable, under heat or in water. Isomer conversion occurred only at the aC in CP or CF, causing the analyte stereoisomer to convert to an epimer. At a GC inlet temperature of 260°C, about 9% conversion occurred for CP and CF. In organic solvents and sterile water, stereoisomers of cis-BF and PM were stable, but slow isomer conversion was observed for CP and CF in water at ambient temperature. However, isomer conversion for CP and CF was relatively insignificant (2-3%) when the GC inlet temperature was kept at ≤ 180°C or when on-column injection was used. Isomer conversion at the αC in water suggests that abiotic processes may also contribute to enantioselectivity observed in the environment for pyrethroids with the asymmetric αC.
