Pigment Orange 34 is an organic compound and an azo compound. It is a commercial orange pigment, i.e. an insoluble colorant. It is also classified as a diarylide pigment, being derived from 3,3'-dichlorobenzidine. It is closely related to Pigment Orange 13, wherein the two tolyl groups are replaced by phenyl groups. [1]

Pigment Orange 34 is a popular component of artist's paints. [2]
