  Description FD & C Red No. 3 is principally the disodium salt of the monohydrate of 9(ocarboxyphenyl)-6-hydroxy-2,4,5,7-tetraiodo-3H- xanthen-3-one.

  The colorant is a brown powder that dissolves in water to give a solution red at neutrality, with a yellow-brown precipitate in acid, and with a red precipitate in base. When dissolved in concentrated sulfuric acid, it yields a brown-yellow solution that evolves iodine and a precipitate of the free acid when heated.
