Cyfluthrin Usage And Synthesis
- DescriptionCyfluthrin is a broad-spectrum synthetic pyrethroid insecticide with both contact and poison action. It is first registered by EPA in 1987 and found in both restricted use and general-use insecticides. Cyfluthrin is used for a wide array of pests in agriculture, in and around the home, and in food handling establishments. These pests include 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. Cyfluthrin is also used in public health situations and for structural pest control. Cyfluthrin is neurotoxic. It could cause organ inflammation in many animal studies and induce skin paresthesia, as well as reproductive problems. Also, Cyfluthrin is highly toxic to fish, aquatic organisms and bees.
- Chemical PropertiesIn pure form this chemical may be colorless crystalline solid or powder. Commercial is a yellowish paste or viscous, yellowish-brown oil. Aromatic odor.
- UsesCyfluthrin is used to control a wide range of insects, especially Lepidoptera, in cereals, fruit, vegetables and cotton. It is also used against migratory locusts and grasshoppers, in stored products, in public health situations and in animal health.
- DefinitionChEBI: A carboxylic ester obtained by formal condensation between 3-(2,2-dichloroethenyl)-2,2-dimethylcyclopropanecarboxylic acid and (4-fluoro-3-phenoxyphenyl)(hydroxy)acetonitrile.
- General DescriptionA viscous amber partly crystalline oil. Used as an insecticide.
- Reactivity ProfileCyfluthrin is a pyrethrine derivative. Incompatible with azocyclotin, and perhaps other azo compounds and organometallics.
- Agricultural UsesInsecticide: Cyfluthrin is a non-systemic insecticide used to control a variety of chewing and sucking insects on cotton, hops, cereals, corn, peanuts, fruit, potatoes and other crops and vegetables. It is also used o control structural pests such as termites.

- Potential ExposureCyfluthrin 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 pathwayThe 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.

- DegradationCyfluthrin 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.
- IncompatibilitiesMay 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 DisposalIncineration 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.
