| 2,4-xylidine | A primary arylamine that is aniline in which the hydrogens at the 2- and 4-positions are replaced by methyl groups. A clear to yellow liquid, it is used in production of certain dyes, pesticides and other chemicals. | 2,4-dimethylaniline |
| 2,5-xylidene | A primary arylamine that is aniline in which the hydrogens at the 2- and 5-positions are replaced by methyl groups. It is used in the manufacture of dyes and other chemicals. | 2,5-dimethylaniline |
| 2,6-xylidine | A primary arylamine that is aniline in which the hydrogens at the 2- and 6-positions are replaced by methyl groups. It is used in the production of some anasthetics and other chemicals. It is a drug metabolite of lidocaine (local anasthetic). | 2,6-dimethylaniline |
| 3,4-xylidine | A primary arylamine that is aniline in which the hydrogens at the 3- and 4-positions are replaced by methyl groups. A low-melting, crystalline solid, it is used in the production of vitamin B2, dyes, pesticides and other chemicals. | 3,4-dimethylaniline |
| 4-nitrosodimethylaniline | A member of the class of dimethylanilines that is N,N-dimethylaniline having a nitroso group at the 4-position. | N,N-dimethyl-4-nitrosoaniline |
| dimethylaniline n-oxide | A member of the class of dimethylanilines that is N,N-dimethylaniline in which the tertiary amino group has been oxidised to give the corresponding N-oxide. | N,N-dimethylaniline N-oxide |
| n,n-dimethylaniline | A tertiary amine that is aniline in which the amino hydrogens are replaced by two methyl groups. | N,N-dimethylaniline |
