Ponceau 4R is a synthetic strawberry red azo dye that is a food colorant dye used in a variety of food products. It is stable to light, heat and acid, but fades in the presence of ascorbic acid. It is usually synthesized from aromatic hydrocarbons.

Ponceau 4R is a monoaze dye that occurs as reddish powder or granules. It is principally the trisodium salt of 2-hydroxy-1-(4-sulfonato-1- naphthylazo)-6,8-naphthalenedisulfonate and subsidiary coloring matters, together with sodium chloride and/or sodium sulfate as the principal uncolored components.

Ponceau 4R consists essentially of trisodium 2-hydroxy-1-(4-sulfonato-1-naphthylazo) naphthalene-6,8-disulfonate and subsidiary colouring matters together with sodium chloride and/or sodium sulphate as the principal uncoloured components.

Ponceau 4R (which is known by more than 100 synonyms including C.I. Food Red 7, Cochineal Red A, and New Coccine) is a synthetic red azo dye used in a range of alcoholic and nonalcoholic beverages, and a variety of foodstuffs including confectionary, desserts, cheeses, meats, preserved fruits, and sauces.
