Use

The toxicity of m-toluidine is similar to thatof o-toluidine. The exposure routes are ingestion, inhalation, and absorption through skin.The toxic effects are methemoglobinemia,anemia, and hematuria. It metabolizes to 2-amino-4-methylphenol, the major componentexcreted in urine. Inhalation of 40-ppm concentration for an hour produced severe poi soning in humans. The oral LD50 value inmice is 740 mg/kg, which is in a range com parable to its o- and p-isomers.The pure liquid is a mild to moderate skinirritant. Its irritating effect on the eyes ofrabbits was strong.m-Toluidine did not induce any carcino genicity in test subjects. This finding is incontrast to its ortho-isomer. Nor did it produce any mutagenic activity.
