[Acute toxicity of l-naphthyl chlorocarbonate and o-isopropoxynitrobenzene]

The investigated compounds given orally to male rats induced pathological changes mainly in the liver. 1-naphthyl chlorocarbonate caused also necrosis of the stomach mucosa. DL50 of o-isopropoxynitrobenzene and 1-naphthyl chlorocarbonate established for male rats after per os administration amounted to 2,75 g/kg and 2,55 g/kg, respectively. Both substances have local irritant effect on the skin and the eye of rabbit--a mild reaction in case of o-isopropoxynitrobenzene and strong one in case of 1-naphthyl chlorocarbonate administration. 1-naphthyl chlorocarbonate has sensitizing properties, while the other compound has not.
