Description

(3-Phenoxyphenyl)Methyl (1S,3R)-3-[(Z)-2-Chloro-3,3,3-Trifluoro-Prop-1-Enyl]-2,2-Dimethyl-Cyclopropane-1-Carboxylate is a high-purity synthetic pyrethroid intermediate of significant commercial importance. This compound is a critical building block for the synthesis of advanced, high-efficacy insecticidal agents used in crop protection and public health. It is primarily required by agrochemical manufacturers and fine chemical producers engaged in the development of next-generation pest control solutions.

Application

• Agrochemical Synthesis: Key intermediate for the production of modern pyrethroid insecticides such as λ-cyhalothrin and γ-cyhalothrin.
• Crop Protection Formulations: Used in manufacturing broad-spectrum insecticides effective against a wide range of lepidopteran, coleopteran, and other pests in major crops.
• Public Health Products: Serves as a precursor for insecticides used in mosquito control and household pest management applications.
• Fine Chemical Research: A valuable chiral synthon for pharmaceutical and advanced material research due to its complex cyclopropane and stereochemical structure.
• Technical Material Production: Supplied to formulators for the creation of technical-grade active ingredients (TGAI).
