  • Applications

    Chlorophacinone (CAS 3691-35-8) is an anticoagulant rodenticide formulated as bait blocks, pellets, or liquids to control rat and mouse populations; in agriculture it helps protect stored grains and crops, in warehouses and food-processing facilities it supports pest management to minimize contamination and losses, in industrial manufacturing facilities it safeguards infrastructure and inventory from rodent damage, and in urban or household settings it is used in professional rodent-control programs and consumer bait products under regulatory oversight.
