Lambda-Cyhalothrin is a pesticide belonging to pyrethroids, a class of man-made insecticides that mimic the structure and insecticidal properties of the naturally-occurring insecticide pyrethrum which comes from the flowers of chrysanthemums. Synthetic pyrethroids, like lambda-cyhalothrin, are often preferred as an active ingredient in insecticides because they remain effective for longer periods of time. Lambda-Cyhalothrin is a mixture of two isomers of the product, the R and S forms in the alpha carbon.
We can provide Lambda-Cyhalothrin cis A stereoisomer ((R)(Z)-(1R)-cis + (S)(Z)-(1S)-cis). This will be of interest to agrochemical sponsors and analytical labs involved in registration of this and other pyrethroids.
