Pigment yellow 139 is an organic compound that is used as a yellow-orange pigment. It is classified as a derivative of isoindoline. This yellow-orange solid is virtually insoluble in most solvents.[1]
The species is prepared by addition of ammonia to o-phthalonitrile to give the diiminoisoindoline, which in turn condenses with barbituric acid.[2]
