Description
Alpha-Cypermethrin is a synthetic pyrethroid pesticide that is widely used in both commercial agricultural applications and consumer products for domestic purposes. It is known for its effectiveness in controlling a broad spectrum of insects.
Uses
Used in Agricultural Industry:
Alpha-Cypermethrin is used as an insecticide for controlling a wide range of insects, particularly Lepidoptera, in various crops such as fruit, vines, vegetables, cereals, beans, beets, cotton, ornamentals, and forestry. Its application helps protect these crops from insect damage, ensuring higher yields and better quality produce.
Used in Public Health:
Alpha-Cypermethrin is also used for insect control in public health settings. It plays a crucial role in managing and preventing the spread of insect-borne diseases, contributing to a healthier environment for communities.
Used in Veterinary Applications:
In addition to its use in agriculture and public health, Alpha-Cypermethrin is utilized for ectoparasite control on animals. It helps protect animals from insect infestations, promoting their overall health and well-being.

Potential Exposure
alpha-Cypermethrin useds 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. alpha-Cypermethrin only is a United States Environmental Protection Agency Restricted Use Pesticide (RUP).
Metabolic pathway
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.

Pyrethroid pesticide, liquid toxic, Hazard Class: 6.1;
Labels: 6.1-Poisonous materials.
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.
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.
Check Digit Verification of cas no
The CAS Registry Mumber 67375-30-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,3,7 and 5 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 67375-30:
(7*6)+(6*7)+(5*3)+(4*7)+(3*5)+(2*3)+(1*0)=148
148 % 10 = 8
So 67375-30-8 is a valid CAS Registry Number.
