The comparative acute mammalian toxicity of 1-chloroacetophenone (CN) and 2-chlorobenzylidene malononitrile (CS).


The comparative acute toxicity of two peripheral sensory irritant materials, 1-chloroacetophenone (CN) and 2-chlorobenzylidene malononitrile (CS), has been investigated in several species of small mammal using solutions in polyethylene glycol 300 for intravenous, intraperitoneal and oral administration, and as pure aerosols for inhalation exposure. Additionally, the comparative potency for inducing primary contact dermatitis was studied. CN and CS were found to be about equitoxic by intravenous and intraperitoneal injection, but CS was significantly less toxic by the oral and inhalation routes and less likely to cause non-lethal tissue damage than CN.
