colourless crystals or white powder | [Uses]
insecticide | [Uses]
α-Cypermethrin is a synthetic pyrethroid pesticide used in large-scale commercial agricultural applications as well as in consumer products for domestic purposes. | [Potential Exposure]
Pyrethroid Insecticide used for the
control of a wide range of chewing and sucking insects
(particularly lepidotera, coleoptera, and hemiptera) in fruit
(including citrus), vegetables, vines, cereals, maize, beet,
oilseed rape, potatoes, cotton, rice, soya beans, forestry,
and other crops. Control of cockroaches, mosquitoes, flies,
and other insect pests in public health; and flies in animal
houses. Also used as an animal ectoparasiticide. zeta-
Cypermethrin only is a United States Environmental
Protection Agency Restricted Use Pesticide (RUP). | [First aid]
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions) if
breathing has stopped, and CPR if heart action has stopped.
Transfer promptly to a medical facility. When this chemical
has been swallowed, get medical attention. Do not induce
vomiting when formulations containing petroleum solvents
are ingested. Otherwise, give large quantities of water and
induce vomiting. Do not make an unconscious person
vomit. | [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. | [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]
Do not discharge into drains
or sewers. Burn in incinerator specifically designed for pes-
ticide disposal or dispose as a Hazardous waste in a landfill
approved and licensed for the disposal of pesticides.
Consult with environmental regulatory agencies for guid-
ance on acceptable disposal practices. Ultimate disposal of
the chemical must consider: the material’s impact on air
quality; potential migration in soil or water; effects on ani-
mal, aquatic, and plant life; and conformance with environ-
mental and public health regulations. | [Definition]
ChEBI: Cypermethrin is 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. It has a role as a pyrethroid ester insecticide, a pyrethroid ester acaricide, an agrochemical and a molluscicide. It is an organochlorine compound, a nitrile, an aromatic ether and a cyclopropanecarboxylate ester. It is functionally related to a 3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylic acid. | [Agricultural Uses]
Insecticide: A U.S. EPA restricted Use Pesticide (RUP) (zeta-Cypermethrin only). Used for the control of a wide range of chewing and sucking insects (particularly Lepidotera, Coleoptera, and Hemiptera) in fruit (including citrus), vegetables, vines, cereals, maize, beet, oilseed rape, potatoes, cotton, rice, soya beans, forestry, and other crops. Control of cockroaches, mosquitoes, flies, and other insect pests in public health; and flies in animal houses. Also used as an animal ectoparasiticide. | [Trade name]

Alpha-cypermethrin is composed of two of the four cis-cypermethrin
isomers (i.e. two of the eight cypermethrin isomers). These are the lRcisaS
and 1ScisaR isomers. The fate of alpha-cypermethrin specifically has been
reported for soils, rat and human. Metabolite analysis was conducted in
enough detail to indicate that the fate of this mixture is very similar to its
fate when presented to biological systems as part of cis-cypermethrin.
Thus reference can be made to the cypermethrin entry for details. The
structure and Scheme numbering used below refers to the cypermethrin
entry. | [Degradation]
Alpha-cypermethrin is stable as a solid but it is readily hydrolysed in
solution under alkaline conditions. By analogy with cypermethrin, the
rate-determining step in dilute solution is nucleophilic attack by OH-.
Half-lives of cis-cypermethrin in river water and sea water at 25 °C
were 21 and 24 days, respectively. Major products were 3-(2,2-dichlorovinyl)-
2,2-dimethylcyclopropanecarboxylic acid (2, DCVA), 3-phenoxybenzaldehyde
(9, 3PBAl) and a-carbamoyl-3-phenoxybenzyl 3-(2,2-
dichlorovinyl)-2,2-dimethylcyclopropanecarboxyltae (the amide 3);
minor products were 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
cis-cy permethrin. |
