Safety
Poison by ingestion and subcutaneous routes. A skin irritant. Mutation data reported. Questionable carcinogen. Has a toxic action upon the liver and can cause fatty degeneration of that organ. Its total effect upon the body seems to take place three different ways. It is toxic to the central nervous system, producing jaundice by action on the liver and spleen, and anemia by destruction of the red blood cells. This action is quite similar to that of aniline, although by no means identical with it. Its high boiling point and the fact that the material is solid at room temperature make it somewhat less hazardous than aniline, particularly at ordinary working temperatures. The literature contains a reference to a permanent injury to an eye due to the use of this material as an eyelash dye. It is considered to be an irritating dye material. When heated to decomposition it emits toxic fumes of NOx.
