Description

1S,3R,αr-Deltamethrin CAS NO 106454-65-3 is a high-purity, single-isomer form of the potent synthetic pyrethroid insecticide deltamethrin. This specific stereochemical configuration is critical for maximizing insecticidal activity and ensuring consistent performance in demanding formulations. It is an essential active ingredient for manufacturers developing advanced agricultural and public health pest control solutions. Industries requiring reliable and effective knockdown agents against a broad spectrum of insects will find this isomerically pure product indispensable.

Application

• Agricultural Insecticides: Formulation of high-efficacy crop protection products for controlling lepidopteran, coleopteran, and dipteran pests in cotton, cereals, and fruits.
• Public Health Products: Key component in manufacturing sprays, coils, and treated materials for mosquito control and the prevention of vector-borne diseases.
• Animal Health: Used in ectoparasiticide formulations for livestock and pets to control ticks, fleas, and flies.
• Professional Pest Management: Serves as an active ingredient in products for structural pest control against cockroaches, ants, and termites.
• Seed Treatment: Incorporated into coating formulations to protect seeds from soil-dwelling insects during germination.
• Research & Development: Used as a reference standard and for developing new, optimized insecticidal formulations and delivery systems.
