slightly beige to beige or pink crystalline mass | [Uses]
3,4-Dimethylaniline (3,4-DMA) has been used to study the electron donor-acceptor (EDA) interaction between 2,3-dicyano-1,4-naphthoquinone (DCNQ) and 3,4-dimethylaniline, in chloroform and dichloromethane. It can also be used for reactions with MoO(X)2(dtc)2 (X = Cl or Br; dtc = diethyldithiocarbamate) in methanol to form ionic imido complexes of the type [MoNAr(dtc)3]2[Mo6O19] or MoNAr(dtc)3]4[Mo8O26]. | [Uses]
3,4-Dimethylaniline is used to study electron donor-acceptor interaction with DCNQ. It is also used as a fine chemical &organic intermediate. | [Definition]
ChEBI: 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. | [Synthesis Reference(s)]
