  • Applications

    Coumatetralyl (CAS 5836-29-3) is an anticoagulant active ingredient used in rodenticide baits to control rats and other gnawing pests. Real-world applications include agricultural rodent control to protect crops, urban and commercial pest management, and stored-product pest protection in warehouses and grain handling facilities through pellet or block bait formulations; it is also used by professional pest-control operators in formulated products, with usage governed by local regulations and formulation limits.
