Diphacinone

Description:

Diphacinone is an anticoagulant rodenticide belonging to the hydroxycoumarin class of compounds. It is primarily used for controlling rodent populations, particularly in agricultural and urban settings. Diphacinone functions by inhibiting vitamin K epoxide reductase, which is essential for the synthesis of clotting factors in the liver, leading to internal bleeding in rodents. This compound is typically presented as a bait formulation, making it effective for pest control. Diphacinone is characterized by its relatively low toxicity to non-target species when used according to label instructions, although it can pose risks to wildlife and pets if ingested in significant amounts. It is a solid at room temperature, with a white to off-white crystalline appearance. The substance is stable under normal conditions but should be stored in a cool, dry place away from incompatible materials. Due to its potential environmental impact, the use of diphacinone is regulated in many regions, and users are advised to follow safety guidelines to minimize risks.
