What is Deltamethrin?

Plain description, key identifiers and synonyms

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.

Uses and applications

What the substance is used for, by industry and function

Insecticides (pyrethroid ester insecticides).

Insecticide.

It is used mostly for crop protection (85% of total production), of which 45% is used on cotton, 25% on fruit and vegetable crops, 20% on cereals, maize and soya beans and the remaining 10% on miscellaneous crops such as coffee, maize and hops. It is also used in public health program (against Chagas' disease and malaria) and to protect stored crops, primarily cereal grains, coffee beans and dry beans. It can be used in animal facilities.

How it is made

Deltamethrin is ... (a) pyrethroid composed of a single isomer of 8 stereoisomers selectively prepared by the esterification of [1R, 3R or cis]-2,2-dimethyl-3-(2,2- dibromovinyl) cyclopropanecarboxylic acid with (alpha S)- or (+)-alpha-cyano-3- phenoxybenzyl alcohol or by selective recrystallization of the racemic esters obtained by esterification of the (1R, 3R or cis)-acid with the racemic or [alpha R, alpha S, or alpha RS or + or -]-alcohol.
