Description

1S,3R,αs-Deltamethrin 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 technical-grade active ingredient for manufacturers of professional and agricultural pest control products targeting a broad spectrum of insects.

Application

• Agricultural Insecticides: Formulation of concentrated solutions and emulsifiable concentrates (EC) for crop protection against lepidopteran, coleopteran, and dipteran pests.
• Public Health Pest Control: Manufacturing of products for mosquito control programs and management of disease vectors.
• Animal Health: Used in the production of ectoparasiticides for livestock, such as pour-on and dip formulations.
• Professional Pest Management: Key component in formulations for termiticides and products for controlling crawling and flying insects in industrial and commercial settings.
• Material Protection: Incorporation into treatments for textiles and other materials to provide long-lasting protection against insect damage.
