PRODUCT INTRODUCTION
description
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.
