The acute oral toxicity of 4-nitrophenyl monochloromethyl phenyl phosphinate was determined in female, albino, Sprague-Dawley rats by using the single dose oral gavage method. LD1, LD50, and LD95 with the 95 confidence limits were calculated by probit analysis. The LD50 was 242 mgkg with the 95 confidence limit 221 mgkg, 265 mgkg. The formulation falls in the very toxic range.
