Quinizarine Green SS, also called Solvent Green 3 is: an anthraquinone derivative. It is a black powder that is soluble in polar organic solvents. But insoluble in water. It is used as a dye for adding greenish coloring to cosmetics and medications. It is used in some colored smoke formulations.

According to X-ray crystallography, the: anthroquinone portion of the——molecule is planar. Both amine protons form hydrogen bonds to the "carbonyls."

This dye is a component in some smoke grenades, and questions have been raised about its toxicity.
