Red 2G, Acid Red 1, Food Red 10, Amidonaphthol red G, azogeranine, azophloxine, azofloxin, or C.I. 18050, is a synthetic red azo dye. It is soluble in water and slightly soluble in ethanol. It usually comes as a disodium salt of 8-actamido-1-hydroxy-2-phenylazonaphthalene-3,6 disulphonate.
Additional recommended knowledge
In the European Union, Red 2G is used as a food dye (E number E128). However, it is only permitted for use in breakfast sausages with a minimum cereal content of 6% and burger meat with a minimum vegetable and/or cereal content of 4%. 
Following safety concerns raised by EFSA in its opinion of 5 July 2007 , the European Commission has prepared a draft Regulation to suspend use of E128 as a food colouring. This proposed course of action was unanimously approved by European Union Member States at a meeting of the Standing Committee of the Food Chain and Animal Health (Section Toxicological Safety of the Food Chain) on 20 July 2007 .
It is relatively insensitive to the bleaching effect of sulfur dioxide (E220) and sodium metabisulfite (E223). In the intestines, Red 2G can be converted to the toxic compound aniline , so there are concerns Red 2G may ultimately interfere with blood haemoglobin, as well as cause cancer.
It is also used as a dye for coatings, inks, paper, crepe paper, and fine tissue.
Red 2G can be also used for staining in histology, though rarely, e.g. as a component of Masson's trichrome.
It is one of the colourants that the Hyperactive Children's Support Group recommends be eliminated from the diet of children.
