Deltamethrin is a cyclopropanecarboxylate ester obtained by formal condensation between 3-(2,2-dibromovinyl)-2,2-dimethylcyclopropanecarboxylic acid and cyano(3-phenoxyphenyl)methanol. It is the active insecticide of the proinsecticide tralomethrin. It has a role as an antifeedant, an agrochemical, an EC 3.1.3.16 (phosphoprotein phosphatase) inhibitor, a calcium channel agonist and a pyrethroid ester insecticide. It is a nitrile, an aromatic ether, an organobromine compound and a cyclopropanecarboxylate ester. It is functionally related to a cis-3-(2,2-dibromovinyl)-2,2-dimethylcyclopropanecarboxylic acid.
