Metabolite Identification
Common NameO-Toluidine
DescriptionThe chemical properties of the toluidines are quite similar to those of aniline and toluidines have properties in common with other aromatic amines. Due to the amino group bonded to the aromatic ring, the toluidines are weakly basic. None of the toluidines is very soluble in pure water, but will become soluble if the aqueous solution is acidic due to formation of ammonium salts, as usual for organic amines. At room temperature and pressure, ortho- and meta-toluidines are viscous liquids, but para-toluidine is a flaky solid. This can be explained by the fact that the p-toluidine molecules are more symmetrical and fit into a crystalline structure more easily. p-Toluidine can be obtained from reduction of p-nitrotoluene. p-Toluidine reacts with formaldehyde to form Troger's base.
