Cypermethrin Usage And Synthesis

Description

Cypermethrin is a synthetic pyrethroid derivative of natural pyrethrins with a good insecticidal action. In vertebrates and invertebrates, cypermethrin acts mainly on the nervous system. It is both a stomach poison and a contact insecticide. Cypermethrin is used as an insecticide in large-scale commercial agricultural applications as well as in consumer products for domestic purposes. Cypermethrin is used to control pests in soybean, leeks, onions, carrots, turnips, swedes, parsnips, viola spp., spinach, black currant, gooseberries, sunflowers, linseeds, groundnuts, barley, and mushrooms.

Description

Form: Odorless crystals (pure); yellow-brown viscous semisolid at ambient temperatures (technical grade)

Chemical Properties

Viscous Semisolid

Chemical Properties

Thick, yellow-brown liquid or semisolid mass (technical product).

Uses

Zeta-cypermethrin is used for the control of Lepidoptera, beetles and aphids in cotton, fruit, vegetables, field crops, ornamentals and forestry. It is also used in public health.

Uses

A potent inhibitor of calcineurin

Uses

Insecticide.

Uses

Synthetic pyrethroid insecticide, usually exists as a mixture of cis and trans isomers. Ectoparasiticide

Definition

ChEBI: A carboxylic ester resulting from the formal condensation between 3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylic acid and the alcoholic hydroxy group of hydroxy(3-phenoxyphenyl)acetonitrile.

Agricultural Uses

Insecticide: A U.S. EPA restricted Use Pesticide (RUP) used to control a variety of insects on cotton, fruit and vegetable crops. Also used in commercial and residential settings, ships, laboratories and food processing plants.

Biological Activity

Type II synthetic pyrethroid insecticide; an extremely potent, cell-permeable inhibitor of calcineurin.

Contact allergens

Pyrethroids, also called pyrethrinoids, are neurotoxic synthetic compounds used as insecticides, with irritant properties. Cypermethrin and fenvalerate have been reported as causing positive allergic patch tests, but only fenvalerate was relevant in an agricultural worker.

Potential Exposure

Pyrethroid insecticide used to control pests on cotton, fruit, and vegetable crops. Also used in commercial and residential settings, ships, laboratories, and food-processing plants. A United States Environmental Protection Agency Restricted Use Pesticide (RUP).

Environmental Fate

Soil. The major soil metabolite was reported to be 3-phenoxybenzoic acid (Hartley and Kidd, 1987).

Metabolic pathway

In cabbage plants, (1R)-cis- and (1R)-trans-isomers of cypermethrin undergo epimerization to (1S)-isomers, cis=trans isomerization, ester bond cleavage, hydroxylation of the phenoxy group in the alcohol moiety or the geminal methyl group in the acid moiety, hydration of the cyano group to an amido group with subsequent hydrolysis to the carboxylic acid, and the conjugation of the carboxylic acid, and alcohols with sugars.

Shipping

UN3349 Pyrethroid pesticide, solid toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous material. UN3352 Pyrethroid pesticide, liquid toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.

Degradation

Zeta-cypermethrin is stable as a solid but it is readily hydrolysed at alkaline pH. Its half-lives at pH values 7 and 9 (25 °C) were 188-635 and 3 days (PM). By analogy with cypermethrin, the major products should be 3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylica cid (2, DCVA), 3-phenoxybenzaldehyde (9, 3PBAl) and a-carbamoyl-3- phenoxybenzyl 3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate (the amide 3); minor products expected are the a-carboxy analogue of 3 (4) and 3-phenoxybenzoic acid (10,3PBA) (see cypermethrin, Schemes la and lb).
Photodecomposition would be expected to be similar to that of cypermethrin. In aqueous solution the DTSo was reported to be 20-36 days (PM).

Toxicity evaluation

Acute oral LD50 for rats: 250-4,150 mg/kg (pure); 7,180 mg/kg (technical grade)

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.

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 40 CFR 165, follow recommendations for the disposal of pes- ticides and pesticide containers.
