Ponceau 6R (also Crystal scarlet, to German, Kristallscharlachrot ') is a red azo dye.

Properties

Ponceau 6R is soluble in water and soluble in a lesser extent in ethanol. Ponceau 6R is used as a food additive E 126, but is not approved in the EU. In addition, is Ponceau 6R, usually as the sodium salt, in histology for staining of fibrin (along with Martin Yellow and blue water ) used in the course of MSB trichrome staining. Alternatively amaranth is used in the trichrome staining. In animals, Ponceau 6R leads in high doses via the formation of Hemiglobin to a hemolytic anemia.
