Used as a potent rodenticide due to its ability to disrupt cellular metabolism by inhibiting key enzymes in the citric acid cycle. Its high toxicity makes it effective in controlling rodent populations, especially in agricultural and urban settings. However, due to its extreme toxicity to humans and non-target animals, its use is highly restricted or banned in many countries. Historically applied in pest control formulations, it has largely been replaced by safer alternatives. Limited use may still occur in specialized industrial or research settings where strict containment is possible.
