PRODUCT INTRODUCTION
description
Fast yellow is 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sodium salt that is 4-aminoazobenzene-3,4'-disulfonic acid in which the protons of both of the sulfo groups have been replaced by sodium ions.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. It has a role as a histological dye.
