Description

Difethialone is a potent second-generation anticoagulant rodenticide belonging to the 4-hydroxycoumarin class. Its high efficacy and palatability make it a critical tool for professional pest management in sensitive environments where resistance to first-generation anticoagulants is a concern. This product is essential for manufacturers of professional and agricultural rodenticide formulations, as well as for public health and vector control programs targeting rodents.

Application

• Primary active ingredient in commercial and professional rodenticide baits (blocks, pellets, and place packs).
• Used in pest control programs for warehouses, agricultural facilities, and food storage sites.
• Critical component in formulations targeting rodent populations resistant to warfarin and other first-generation anticoagulants.
• Employed in municipal and public health initiatives for urban rodent management.
• Integrated into pest control strategies for livestock farms to prevent disease transmission and feed contamination.
• Used in the manufacturing of tracking powders for rodent control.

Quality Control

Our Difethialone is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. Every lot is analyzed to confirm identity, potency, and the absence of significant impurities. A comprehensive Certificate of Analysis (COA) detailing purity, related substances, and other critical parameters is 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 place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation.
