Pigment Yellow 74 is an azo dye and classified as an arylide yellow. It is an intensely yellow-green solid. It is prepared by azo coupling of the diazonium derivative of 2-methoxy-4-nitroaniline with 2-methoxyacetoacetanilide. It is a flat molecule, enforced by the hydrogen-bonding via the ketohydrazide group.

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