Description

cis-Permethrin is a specific stereoisomer of the widely used synthetic pyrethroid insecticide, permethrin. This compound is valued for its potent insecticidal activity, particularly against a broad spectrum of agricultural pests and disease vectors. It is a critical active ingredient for manufacturers in the agrochemical, public health, and professional pest control industries seeking effective and reliable insecticide formulations.

Application

• Agricultural Insecticides: Formulated for the control of lepidopteran, coleopteran, and other insect pests in crops such as cotton, fruits, and vegetables.
• Public Health Vector Control: Used in products for mosquito control programs to combat malaria, dengue, and other mosquito-borne diseases.
• Professional Pest Management: A key component in formulations for professional-grade termiticides, ant baits, and perimeter sprays for structural pest control.
• Animal Health Products: Incorporated into ectoparasiticide treatments for livestock, such as pour-ons and dips, to control ticks, lice, and flies.
• Textile and Material Protection: Used in treatments to impart insect resistance to fabrics, military uniforms, and outdoor gear.
• Household Insecticides: Serves as an active ingredient in various consumer insecticide sprays, aerosols, and foggers.

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 isomer content and assay, GC for residual solvents, and identification by IR and NMR spectroscopy. Certificates of Analysis (COA) detailing all specifications are provided with each shipment to support your quality assurance protocols.

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 to prevent moisture absorption and contamination.
