MedKoo Cat#: 464316 | Name: Ponceau 4R free acid

Description:

WARNING: This product is for research use only, not for human or veterinary use.

Ponceau 4R is a synthetic colorant that may be used as a food coloring. It is denoted by E Number E124. Ponceau 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.
