Cyhalothrin (ISO common name [3]) is an organic compound that, in specific isomeric forms, is used as a pesticide. [4] It is a pyrethroid, a class of synthetic insecticides that mimic the structure and properties of the naturally occurring insecticide pyrethrin which is present in the flowers of Chrysanthemum cinerariifolium. Pyrethroids, such ...
Cyfluthrin is a pyrethroid insecticide and common household pesticide. It is a complex organic compound and the commercial product is sold as a mixture of isomers.Like most pyrethroids (MoA 3a), [1] it is highly toxic to fish and invertebrates, but it is far less toxic to humans. [2]
Over the subsequent decades these derivatives were followed with other proprietary compounds such as fenvalerate, lambda-cyhalothrin and beta-cyfluthrin. Most patents have now expired, making these compounds cheap and therefore popular (although permethrin and fenvalerate have not been re-registered under the 91/414/EEC process).
Cypermethrin (CP) is a synthetic pyrethroid used as an insecticide in large-scale commercial agricultural applications as well as in consumer products for domestic purposes.
In 2016 insecticides were estimated to account for 18% of worldwide pesticide sales. [2] Worldwide sales of insecticides in 2018 were estimated as $ 18.4 billion, of which 25% were neonicotinoids, 17% were pyrethroids, 13% were diamides, and the rest were many other classes which sold for less than 10% each of the market.

Quinalphos is an organothiophosphate chemical chiefly used as a pesticide. It is a reddish-brown liquid. The chemical formula is C 12 H 15 N 2 O 3 PS, and IUPAC name O,O-diethyl O-quinoxalin-2-yl phosphorothioate. [1]
Tefluthrin (X=CH 3) is manufactured by the esterification of cyhalothrin acid chloride [6] with 4-methyl-2,3,5,6-tetrafluorobenzyl alcohol. [7] The latter was a novel compound when tefluthrin was invented [ 8 ] and the choice of routes to it has been discussed.
