Ponceau 2R
Ponceau 2R, Xylidine ponceau, Ponceau G, Red R, Acid Red 26, Food Red 5, or C.I. 16150 is a red azo dye used in histology for staining. It is easily soluble in water and slightly in ethanol. It usually comes as a disodium salt. Xylidine ponceau is mostly used only in the Masson's trichrome stain as a red counterstain, where it imparts orange hue to the red-stained cytoplasm In cell biology, the cytoplasm is all of the material within a eukaryotic cell, enclosed by the cell membrane, except for the cell nucleus. The material inside the nucleus and contained within the nuclear membrane is termed the nucleoplasm. ...ic structures. Its other names are: Acetacid red J, Acidal ponceau G, Acid leather red KPR, Acid leather red P2R, Acid leather scarlet IRW, Acid ponceau R, Acid ponceau 2RL, Acid ponceau special, Acid scarlet, Acid scarlet 2RL, Acid scarlet 2RN, Acilan ponceau RRL, Ahcocid fast scarlet R, Aizen ponceau RH, Amacid lake scarlet 2R, Amacid scarlet 2R, Brilliant ...

It is denoted by E Number E124. Its chemical name is 1-(4-sulfo-1-napthylazo)-2-napthol-6,8-disulfonic acid, trisodium salt. ''Ponceau'' (17th century French for "poppy-coloured") is the generic name for a family of azo dyes. Ponceau 4R is a strawberry red azo dye which can be used in a variety of food products, and is usually synthesized from aromatic hydrocarbons; it is stable to light, heat, and acid but fades in the presence of ascorbic acid.

Ponceau 6R
Ponceau 6R, or Crystal ponceau 6R, Crystal scarlet, Brilliant crystal scarlet 6R, Acid Red 44, or C.I. 16250, is a red azo dye. It is soluble in water and slightly soluble in ethanol. It was used as a food dye, formerly having E number E126. It is also used in histology Histology, also known as microscopic anatomy or microanatomy, is the branch of biology which studies the microscopic anatomy of biological tissues. Histology is the microscopic counterpart to gross anatomy, which looks at larger structures vis ..., for staining fibrin with the MSB Trichrome stain. It usually comes as disodium salt. Amaranth is a closely related azo dye, also usable in trichrome staining. References Azo dyes Food colorings Staining dyes Naphthalenesulfonates 2-Naphthols Acid dyes {{Ingredient-stub ...
