63402-73-3 Usage
Uses
Used in Agricultural Applications:
Permethrin is used as an insecticide in agricultural settings to control a wide range of pests that can damage crops and reduce yields. Its broad-spectrum activity makes it effective against various insects, helping to protect crops and ensure a stable food supply.
Used in Residential and Commercial Applications:
Permethrin is also used in residential and commercial settings to control pests such as mosquitoes, ticks, fleas, and bedbugs. It can be applied to various surfaces, including walls, floors, and furniture, to create a protective barrier against insect infestations. This helps to maintain a clean and healthy living and working environment.
Used as an Insect Repellent:
In addition to its insecticidal properties, Permethrin can also be used as an insect repellent. It can be applied to clothing, tents, and other outdoor gear to provide protection against insect bites and reduce the risk of insect-borne diseases.
Overall, 3-phenoxybenzyl 2-(4-chlorophenoxy)-3-methylbutanoate, or Permethrin, is a versatile and effective insecticide and repellent that plays a crucial role in protecting crops, homes, and public health from the damaging effects of various insect species.
Check Digit Verification of cas no
The CAS Registry Mumber 63402-73-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,4,0 and 2 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 63402-73:
(7*6)+(6*3)+(5*4)+(4*0)+(3*2)+(2*7)+(1*3)=103
103 % 10 = 3
So 63402-73-3 is a valid CAS Registry Number.

Quantitative structure activity relationship studies in pyrethroid esters derived from substituted 3-methyl-2-phenoxybutanoic acids against Culex quinquefasciatus
Mathew, Nisha,Subramanian,Kalyanasundaram

QSAR studies in relation to three physicochemical substituent parameters, lipophilicity, electronic and steric factors have been carried out with pyrethroid esters derived from substituted 3-methyl-2-phenoxybutanoic acids against Culex quinquefasciatus applying multiple regression analysis by grouping the esters into three based on their alcohol moiety. In the case of 3-phenoxybenzyl and α-cyano-3-phenoxybenzyl esters the larvicidal activity is mainly influenced by the lipophilic and electronic nature of the substituent at 4-position of the phenyl ring of the acid moiety. For adulticidal activity the lipophilicity of the substituent at 4-position followed by that of the substituents at 2-and 3-positions along with the steric effect are the important factors for 3-phenoxybenzyl and α-cyano-3-phenoxybenzyl esters. The larvicidal and adulticidal activities of 3,4-methylenedioxybenzyl esters are influenced by electronic factor followed by steric effect of the substituent.
