Quick and convenient construction of lambda-cyhalothrin.

In the case of lambda-cyhalothrin, although multiple strategies of hapten synthesis have been published, their synthetic routes still have room for optimization (,, ) .Gao et al. reported multi-step synthesis of pyrethroid hapten (Fig. 2, a), yet the method suffered from highly toxic reagent (some other pyrethroid hapten synthesis methods also had this problem, see Fig. 2, c), low overall.

Lambda Cyhalothrin Synthesis Essay

Lambda-cyhalothrin consists of two of the four enantiomers of cyhalothrin. It was first evaluated by JMPR in 1984 (T, R) and periodic re-evaluation conducted in 2007 (T) and 2008 (R). A group of ADI.

CN1508124A - Method for synthesizing lambda-cyhalothrin.

The method for synthesizing cyfluthrin includes five steps: A. making p fluorobenzaldehyde as raw material undergo the process of bromination reaction to obtain 3-bromo-4-fluorobenzaldehyde; B. making 3-bromo-4-fluorobenzaldehyde and ethanediol implement condensation reaction to obtain the correspondent aldehyde acetal; C. making said aldehyde acetal and sodium phenolate implement.SUMMARY A synthetic pyrethroid insecticide which is approved for use in the EU. It has a low aqueous solubility, is relatively volatile, is non mobile and, based on chemical properties, there is a low risk of it leaching to ground water. Lambda cyhalothrin is highly toxic to mammals and is a known irritant.Cyfluthrin and cyhalothrin are similar in structure, differing principally in substitution of a trifluoromethane in cyhalothrin for a chlorine atom in cyfluthrin and substitution of a fluorine on one of the phenoxybenzyl ether aromatic rings. The cyhalothrin use profile is similar to that for cyfluthrin.


Lambda-cyhalothrin is an enriched isomeric form of the two biologically active diastereoisomeric pairs of isomers of cyhalothrin. It is mainly used for plant protection purposes as a non-systemic broad spectrum insecticide in a wide range of crops worldwide.Lambda-cyhalothrin is a pyrethroid insecticide. Pyrethroids are synthetic chemical analogues of pyrethrins, which are naturally occurring insecticidal compounds produced in the flowers of.

Lambda Cyhalothrin Synthesis Essay

Lambda Cyhalothrin Synthesis Essay

Cyhalothrin is the ISO common name for an organic compound that, in specific isomeric forms, is used as a pesticide. 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.

Lambda Cyhalothrin Synthesis Essay

The comparative metabolism of gamma-cyhalothrin with or without enantiomer pari A and cyhalothrin revealed that enantiomer pair A had little or no effect on the absorption, distribution, tissue retention, or metabolic profiles, implying that enantiomers of cyhalothrin behave independently.
