Description

cis-Chlorfenvinphos is an organophosphate insecticide and acaricide of significant commercial and agricultural importance. Its primary value lies in its potent activity against a broad spectrum of soil-dwelling and foliar pests, offering effective crop protection solutions. This compound is essential for agricultural producers, pest control formulators, and research institutions focused on developing and applying targeted insect control strategies.

Application

• Agricultural Insecticide: Control of soil insects such as rootworms, cutworms, and wireworms in various crops including corn, potatoes, and vegetables.
• Veterinary Parasiticide: Used in ectoparasiticide formulations for livestock, targeting ticks, lice, and flies.
• Public Health Pest Control: Formulation into products for controlling flies, mosquitoes, and other public health pests in non-crop areas.
• Industrial & Structural Pest Management: Component in termiticide and general insecticide products for soil treatment around structures.
• Chemical Intermediate: Serves as a key synthetic intermediate in the production of other specialized organophosphorus compounds.
• Research & Development: Reference standard and active ingredient for efficacy and environmental fate studies in agrochemical research.

Quality Control

Our cis-Chlorfenvinphos is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay by HPLC and identification by IR spectroscopy, to confirm identity and potency. A detailed Certificate of Analysis (COA) documenting all quality parameters is provided with every 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). This material is easily oxidized (store under inert atmosphere) and is sensitive to strong alkali/organic solvent. Keep away from heat, sparks, open flames, and incompatible materials. For long-term storage, consider an inert gas blanket.
