Description

cis-Permethrin is a specific, high-purity stereoisomer of the synthetic pyrethroid insecticide permethrin, distinguished by its cis-configuration around the cyclopropane ring. This precise chemical structure is critical for achieving optimal insecticidal activity and stability in advanced formulations. It is an essential technical-grade active ingredient for manufacturers developing professional and agricultural pest control solutions. Key industrial users include producers of public health insecticides, agricultural chemicals, and animal health products.

Application

• Primary active ingredient in the synthesis of high-performance insecticidal formulations for agricultural use.
• Key component in manufacturing public health insecticides for mosquito and vector control programs.
• Used in the production of professional pest control products for commercial and residential settings.
• Intermediate in the development of animal health ectoparasiticides for livestock and pets.
• Essential raw material for creating long-lasting insecticidal treatments for textiles and materials.
• Used in research and development of new insecticide chemistries and synergistic mixtures.

Quality Control

Our cis-Permethrin is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Quality is verified through comprehensive analytical testing including HPLC for assay and isomer ratio, GC for residual solvents, and standard pharmacopoeial identification tests. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming compliance with agreed technical specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Keep away from heat, sparks, and open flame. The container should be kept tightly sealed when not in use to prevent moisture absorption and contamination.
