DESCRIPTION
Allura Red occurs as a red-brown powder or granule. It is principally the disodium salt of 6-hydroxy-5-[(2-methoxy-5-methyl-4-sulfophenyl)azo]-2-naphthalenesulfonic acid. It dissolves in water to give a solution red at neutrality and in acid and dark red in base. It is insoluble in ethanol.
