N-Methylaniline (NMA) is an aniline derivative. It is an organic compound with the chemical formula C 6 H 5 NH(CH 3 ). The substance is a colorless viscous liquid , Samples turn brown when exposed to air.
N-Methylation of aniline with methanol at elevated temperatures over acid catalysts gives N-methylaniline and N,N-dimethylaniline: C 6 H 5 NH 2 + 2 CH 3 OH → C 6 H 5 N(CH 3) 2 + 2H 2 O. N-Methylaniline and N,N-dimethylaniline are colorless liquids with boiling points of 193–195 °C and 192 °C, respectively. These derivatives are of ...
N,N-Dimethylaniline (DMA) is an organic chemical compound, a substituted derivative of aniline. It is a tertiary amine, featuring a dimethylamino group attached to a phenyl group. This oily liquid is colourless when pure, but commercial samples are often yellow. It is an important precursor to dyes such as crystal violet.
o-Toluidine is absorbed through inhalation and dermal contact as well as from the gastrointestinal tract. [19] [13] [20] [21]The metabolism of o-toluidine involves many competing activating and deactivating pathways, including N-acetylation, N-oxidation, and N-hydroxylation, and ring oxidation.

4-Chloro-o-toluidine (4-COT, 4-chloro-2-methylaniline) is the organic compound with the formula CH 3 C 6 H 3 Cl(NH 2). It is a colorless solid. The compound is produced as an intermediate to the pesticide chlordimeform and a precursor to some azo dyes. Production has declined after it was shown to be highly carcinogenic.
Trimethylaniline is a building block to a variety of bulky ligands. Condensation with glyoxal gives the 1,2-diimine ligands.An example is glyoxal-bis(mesitylimine), a yellow solid that is synthesized by condensation of 2,4,6-trimethylaniline and glyoxal.
