Description

α-Cyano-3-Phenoxybenzyl [1S-[1Alpha(R*),3Alpha]]-3-(2,2-Dichlorovinyl)-2,2-Dimethylcyclopropanecarboxylate is a high-purity, single-isomer synthetic pyrethroid intermediate. This compound is critical for the production of advanced, high-efficacy insecticidal formulations. It is primarily required by agrochemical manufacturers and research institutions developing next-generation crop protection products and public health insecticides.

Application

• Agrochemical Synthesis: Key chiral intermediate for the manufacture of high-performance pyrethroid insecticides like deltamethrin and its analogs.
• Crop Protection Formulations: Used in creating concentrated technical materials for foliar sprays and seed treatment products targeting a broad spectrum of pests.
• Public Health Insecticides: Serves as a precursor in formulations for mosquito control, household insect sprays, and other vector management solutions.
• Chemical Research & Development: Employed in academic and industrial R&D for studying structure-activity relationships (SAR) and developing novel insecticidal compounds.
• Specialty Chemical Manufacturing: Utilized in the synthesis of other fine chemicals where the specific cyclopropane carboxylate structure is required.
