General description

o-Aminoazotoluene (AAT) is categorized as a Class 2B carcinogen by the international agency for research on cancer (IARC). This class of azo dyes are widely used as colorants in a variety of products including leather, cosmetics, paper, toys, plastics, pharmaceuticals, textiles, paints, food, leather, etc. Primary aromatic amines (PAAs) are most commonly used as starting compounds in the production of azo dyes and can often migrate into foodstuffs from food packaging materials. AAT finds applications in coloring oils, fats, and waxes.
This compound is listed in the SVHC (Substances of very high concern) candidate list of ECHA (European Chemicals Agency)
o-Aminoazotoluene (AAT) is a carcinogenic primary amino azo dye.1

Application

o-Aminoazotoluene may be used as an analytical reference standard for the quantification of the analyte in:
  • Dyes, cosmetics, inks and finger paints using liquid chromatography coupled to mass spectrometry (LC-MS).
  • Commercial samples including food packaging plastic, multilayer plastic laminates and recycled paperboard categories using liquid chromatography coupled to mass spectrometry (LC-MS) technique.

AAT has been used as reference standard in determination of aromatic amines from azo colorants in toys using HPLC.2
