It is stable in neutral, acidic or alkaline solutions and is classified as "not readily biodegradable" with "low bioaccumulation potential". It is used as a chemical intermediate for azo coupling component 17 and the dyes disperse yellow 5 and acid blue 29. WebN,N-Dimethylaniline ( DMA) is an organic chemical compound, a substituted derivative of aniline. It consists of a tertiary amine, featuring dimethylamino group attached to a phenyl group.

2-Nitroaniline C6H6N2O2 - PubChem

In aniline, the C−N bond length is 1.41 Å, compared to 1.47 Å for cyclohexylamine, indicating partial π-bonding between N and C. The C(aryl)-NH2 distance in anilines is highly sensitive to substituent effects. This distance is 1.34 Å in 2,4,6-trinitroaniline vs 1.44 Å in 3-methylaniline. The amine in anilines is a slightly pyramidalized molecule, with hybridization of the nitrogen somewhere between sp and sp . The nitrogen is described as having high p character.
