Pigment Yellow 83 is an organic compound that is classified as a diarylide pigment. It is used as a yellow colorant.
The compound is synthesized from three components. Treatment of 2,5-dimethoxy-4-chloroaniline with diketene gives an acetoacetylated aniline. This compound is then coupled to the bisdiazonium salt obtained from 3,3'-dichlorobenzidine.China Organic Pigments suppliers
