Description

(1R)-trans-3-Cyhalothrin is a high-purity, single-isomer synthetic pyrethroid insecticide. This compound matters for its potent and selective insecticidal activity, offering enhanced efficacy and potentially reduced environmental impact compared to racemic mixtures. It is primarily needed by manufacturers in the agrochemical industry for formulating advanced crop protection products targeting a broad spectrum of pests.

Application

• Agricultural Insecticides: A key active ingredient in formulations for protecting crops such as cotton, soybeans, fruits, and vegetables from lepidopteran, coleopteran, and other insect pests.
• Public Health Pest Control: Used in the manufacture of products for controlling disease-vector insects like mosquitoes and flies.
• Professional Pest Management: Incorporated into solutions for structural and turf pest control by professional applicators.
• Animal Health: Potential use in ectoparasiticide formulations for livestock.
• Research & Development: Serves as a critical reference standard and intermediate in the synthesis and study of novel pyrethroid compounds.

Quality Control

Our (1R)-trans-3-Cyhalothrin is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including chiral purity assay and impurity profiling, to ensure it meets exacting specifications for agrochemical active ingredients. A Certificate of Analysis (COA) documenting identity, purity, and related substances is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at controlled room temperature (15-25°C). This material is easily oxidized and should be kept under an inert atmosphere (e.g., nitrogen) for long-term storage. Keep away from heat, sparks, and open flame.
