It is used as a food dye and has the E number E129. Allura Red AC was originally introduced in the United States as a replacement for the use of amaranth as a food coloring.; Allura Red AC is one of many High Production Volume Chemicals. Some manufacturers of Allura Red AC include: Asim Products, Sanchi Chemicals Pvt. Ltd., and Warner-Jenkinson Europe Ltd.; Upon its introduction into the market, there were fears that Allura Red AC was carcinogenic; however, studies have since shown that this is not the case.[citation needed] The initial reports of its consumption causing tumors have since been shown to have been caused by the presence of para-cresidine.[citation needed] Although para-cresidine is an important reactant in the manufacture of Allura Red AC and is a known carcinogen, further studies conducted since have found no trace of para-cresidine to be present in food-grade Allura Red AC.[citation needed]. 6-Hydroxy-5-[(2-methoxy-5-methyl-4-sulfophenyl)azo]-2-naphthalenesulfonic acid, 9CI Allura Red Allura red ac dye C.I. 16035 C.I.

These are organic aromatic compounds that contain a naphthalene moiety that carries a sulfonic acid group at the 2-position. Naphthalene is a bicyclic compound that is made up of two fused benzene ring. 2-naphthalene sulfonates Organic compounds Benzenoids Naphthalenes Naphthalene sulfonic acids and derivatives Aromatic homopolycyclic compounds 1-hydroxy-2-unsubstituted benzenoids 1-sulfo,2-unsubstituted aromatic compounds 2-naphthalene sulfonic acids and derivatives Alkyl aryl ethers Anisoles Azo compounds Benzenesulfonic acids and derivatives Benzenesulfonyl compounds Hydrocarbon derivatives Methoxyanilines Methoxybenzenes Naphthols and derivatives Organic oxides Organopnictogen compounds Organosulfonic acids Phenoxy compounds Propargyl-type 1,3-dipolar organic compounds Sulfonyls Toluenes 1-hydroxy-2-unsubstituted benzenoid 1-sulfo,2-unsubstituted aromatic compound 2-naphthalene sulfonate 2-naphthalene sulfonic acid or derivatives 2-naphthol Alkyl aryl ether Anisole Aromatic homopolycyclic compound Arylsulfonic acid or derivatives Azo compound Benzenesulfonate Benzenesulfonyl group Ether Hydrocarbon derivative Methoxyaniline Methoxybenzene Monocyclic benzene moiety Organic 1,3-dipolar compound Organic nitrogen compound Organic oxide Organic oxygen compound Organic sulfonic acid or derivatives Organonitrogen compound Organooxygen compound Organopnictogen compound Organosulfonic acid Organosulfonic acid or derivatives Organosulfur compound Phenol ether Phenoxy compound Propargyl-type 1,3-dipolar organic compound Sulfonyl Toluene logp -0.35 ALOGPS logs -4.35 ALOGPS solubility 2.00e-02 g/l ALOGPS melting_point >300 °C logp -0.44 ChemAxon pka_strongest_acidic -3 ChemAxon pka_strongest_basic -1.7 ChemAxon iupac 6-hydroxy-5-[(E)-2-(2-methoxy-5-methyl-4-sulfophenyl)diazen-1-yl]naphthalene-2-sulfonic acid ChemAxon average_mass 452.458 ChemAxon mono_mass 452.034806878 ChemAxon smiles COC1=C(C=C(C)C(=C1)S(O)(=O)=O)\N=N\C1=C(O)C=CC2=CC(=CC=C12)S(O)(=O)=O ChemAxon formula C18H16N2O8S2 ChemAxon inchi InChI=1S/C18H16N2O8S2/c1-10-7-14(16(28-2)9-17(10)30(25,26)27)19-20-18-13-5-4-12(29(22,23)24)8-11(13)3-6-15(18)21/h3-9,21H,1-2H3,(H,22,23,24)(H,25,26,27)/b20-19+ ChemAxon inchikey UQWIHFJXDRNUDP-FMQUCBEESA-N ChemAxon polar_surface_area 162.92 ChemAxon refractivity 111.56 ChemAxon polarizability 43.42 ChemAxon rotatable_bond_count 5 ChemAxon acceptor_count 10 ChemAxon donor_count 3 ChemAxon physiological_charge -2 ChemAxon formal_charge 0 ChemAxon Specdb::CMs 20057 Specdb::CMs 43008 Specdb::CMs 171574 Specdb::NmrOneD 116458 Specdb::NmrOneD 116459 Specdb::NmrOneD 116460 Specdb::NmrOneD 116461 Specdb::NmrOneD 116462 Specdb::NmrOneD 116463 Specdb::NmrOneD 116464 Specdb::NmrOneD 116465 Specdb::NmrOneD 116466 Specdb::NmrOneD 116467 Specdb::NmrOneD 116468 Specdb::NmrOneD 116469 Specdb::NmrOneD 116470 Specdb::NmrOneD 116471 Specdb::NmrOneD 116472 Specdb::NmrOneD 116473 Specdb::NmrOneD 116474 Specdb::NmrOneD 116475 Specdb::NmrOneD 116476 Specdb::NmrOneD 116477 Specdb::MsMs 105039 Specdb::MsMs 105040 Specdb::MsMs 105041 Specdb::MsMs 171444 Specdb::MsMs 171445 Specdb::MsMs 171446 Specdb::MsMs 2662366 Specdb::MsMs 2662367 Specdb::MsMs 2662368 Specdb::MsMs 3015684 Specdb::MsMs 3015685 Specdb::MsMs 3015686 HMDB32884 #<Reference:0x000055ce3346bd40>
