Pigment Yellow 10 is an organic compound that is classified as a monoazopyrazolone pigment. It is used as a yellow colorant, notably as yellow road marking on highways in the US.
The compound is synthesized by coupling the diazonium salt derived from dichloroaniline with the pyrazolone. [1] The structure of the dye, as determined by X-ray crystallography, consists of planar molecule with a C=O bond and two hydrazone groups. [2]
