Aminoazobenzenes (AABs) are a class of compounds containing the azo group, which renders them colored. They have been used as dyes for fabrics, polishes, and food. 4-dimethylaminoazobenzene (DMAB), was used to color margarine.
This compound is listed in the SVHC (Substances of very high concern) candidate list of ECHA (European Chemicals Agency)

Application

It is intended to be used as a certified reference material (CRM) for calibration in chromatography and other analytical techniques.
The 4-Aminoazobenzene CRM can also be used as given below:

  • To study the spectral characteristics of 1-(2,4-diamino phenylazo) naphthalene and 4-aminoazobenzene by tautomerization and inclusion complexation
  • To study the inclusion complexes of ß-cyclodextrin (ß-CD) with 4-hydroxyazobenzene and 4-aminoazobenzene
  • In the detection of 4-aminoazobenzene using copper nanoclusters prepared using ascorbic acid
