CAS 108-44-1

m-Toluidine is a colorless, clear, viscous liquid. m-Toluidine tend to darken on storage on air and light. It is readily soluble in diethyl ether, ethanol, acetone, chloroform and most organic solvents. It is poorly soluble in water, but dissolves in acidic aqueous solution. It can be distillated with steam. m-Toluidine show conventional aromatic amine properties. It is a weak basic compound, able to form salts, can be diazotated. Electrophilic substitution occurs into ortho- and para positions with regard to amino-group. m-Toluidine is toxic if inhaled, ingested, or absorbed through the skin. It is suspected human carcinogen.
