Description

Epi-γ-Cyhalothrin is a high-purity, single-isomer form of the broad-spectrum pyrethroid insecticide γ-cyhalothrin. This compound matters for its enhanced biological activity and specificity, offering a more targeted and potentially more environmentally considerate pest control solution compared to its isomer mixtures. It is primarily needed by manufacturers in the agrochemical industry formulating advanced crop protection products, as well as by research institutions developing next-generation insecticidal agents.

Application

• Agricultural Insecticides: A key active ingredient in formulations for controlling a wide range of sucking and chewing pests in crops such as cotton, soybeans, and cereals.
• Public Health Pest Control: Used in products targeting disease-vector insects like mosquitoes and flies, contributing to malaria and dengue fever control programs.
• Professional Pest Management (PMP): Incorporated into solutions for the control of ants, cockroaches, and other urban pests in commercial and residential settings.
• Animal Health: Potential use in ectoparasiticide products for livestock to control ticks, lice, and flies.
• Research & Development: Serves as a critical reference standard and intermediate in the synthesis and study of novel pyrethroid compounds.
• Termiticide Formulations: Used in soil treatment and wood preservation products for long-term protection against termite damage.
• Stored Product Protection: Applied to protect grains and other commodities from infestation during storage.

Quality Control

Our Epi-γ-Cyhalothrin is manufactured under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including chiral HPLC for isomeric purity and identity confirmation, to ensure it meets precise specifications. Certificates of Analysis (COA) detailing purity, related substances, and physical parameters are provided with every shipment to guarantee consistent quality and traceability for your formulations and research.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term stability. Keep away from heat, sparks, and open flame.
