Also found in: Encyclopedia, Wikipedia.

nitrophenol

a parasiticide which is applied to buildings and fixtures. Can cause poisoning manifested as high fever, dyspnea, stumbling gait, terminal convulsions, a short course of a few hours and a high mortality rate. A substituted nitrophenol (disophenol) is used as an anthelmintic against blood-sucking nematodes such as hookworms and Haemonchus spp.
