Acute toxicity and primary irritancy of 2-amino-3,5-dicyano-4-o-chlorophenyl-6-ethoxypyridine.

abstract：:Methyl 2,2-difluoromalonyl fluoride (MMF) is highly toxic by inhalation producing mortality in rats exposed for 4 hours to 0.55 mg/L. Repeated inhalation exposures of rats to 0.009 mg/L produced irritation but no other signs of a toxic response. Mortality was encountered following repeated exposures to 0.066 mg/L. ...
