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]
It is prepared by addition of ammonia to phthalonitrile to give diiminoisoindole, which in turn condenses with barbituric acid.[2]
