Preparation

4-(Phenyldiazenyl)benzenamine (C.I.Solvent Yellow 1, C.I. 11000)?disulfonated.

Definition

ChEBI: An organic sodium salt that is 4-aminoazobenzene-3,4'-disulfonic acid in which the protons of both of the sulfo groups have been replaced by sodium ions. It is used as a biological stain. It was formerly used as a food coloring agent (E105), but its use in food or drinks is now forbidden.
