Description

(1S)-trans-3-Cyhalothrin is a high-purity, single-isomer synthetic pyrethroid insecticide. This compound matters for its potent and targeted insecticidal activity, offering enhanced efficacy and potentially reduced environmental impact compared to racemic mixtures. It is primarily needed by manufacturers in the agrochemical industry for formulating advanced crop protection products, as well as by research institutions developing next-generation pest control solutions.

Application

• Agricultural Insecticide Formulations: Key active ingredient in products for controlling a broad spectrum of pests in crops such as cotton, soybeans, and vegetables.
• Public Health Pest Control: Used in formulations for mosquito and fly control programs to combat vector-borne diseases.
• Professional Pest Management (PM): Incorporated into products for structural and perimeter pest control against ants, cockroaches, and other urban pests.
• Animal Health: Potential use in ectoparasiticide products for livestock.
• Chemical Intermediate: Serves as a critical chiral building block for the synthesis of more complex agrochemicals.
• Research & Development: Reference standard and active material for efficacy, toxicology, and environmental fate studies.
