Disperse Red 9, or 1-(methylamino)anthraquinone, is a red dye derived from anthraquinone.

Disperse Red 9 is used in some older red and violet-red colored smoke formulations.

It is used in the M18 colored smoke grenade and also often in dye packs.

Its smoke-producing properties can be improved by coating the dye particles with an inert material, e.g. an epoxy resin.
