Chemical compound

Pigment Yellow 74 is an azo dye with intense yellow-green coloration.

It is popular in tattoo inks. It is prepared by azo coupling of the diazonium derivative of 4-nitro-2-methoxyaniline with acetoacetanilide.

Pigment Yellow 74 is a popular component of artist's paints and tattoo inks.
