Description

(1R)-trans-λ-Cyhalothrin is a highly potent and stereochemically pure synthetic pyrethroid insecticide. This specific isomer offers superior insecticidal activity and environmental stability compared to mixed-isomer formulations, providing exceptional value for advanced agrochemical formulations. It is essential for manufacturers developing high-performance crop protection products targeting a broad spectrum of pests in agriculture and public health.

Application

• Agricultural Insecticides: Formulation of foliar sprays and seed treatments for controlling lepidopteran, coleopteran, and dipteran pests in crops like cotton, soybeans, and vegetables.
• Public Health Pest Control: Key active ingredient in formulations for mosquito control programs to combat vector-borne diseases.
• Professional Pest Management (PMP): Used in products for the control of ants, cockroaches, termites, and other structural pests.
• Animal Health: Incorporation into ectoparasiticide products for livestock and pets.
• Material Protection: Protection of stored grains and other commodities from insect infestation.
• Technical-Grade Synthesis: Serves as a high-purity intermediate for the synthesis of other advanced pyrethroid compounds.
