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 Azo compounds Benzenesulfonic acids and derivatives Benzenesulfonyl compounds Hydrocarbon derivatives Naphthols and derivatives Organic aluminium salts Organic cations Organic oxides Organooxygen compounds Organopnictogen compounds Organosulfonic acids Sulfonyls 1-hydroxy-2-unsubstituted benzenoid 1-sulfo,2-unsubstituted aromatic compound 2-naphthalene sulfonate 2-naphthalene sulfonic acid or derivatives 2-naphthol Aromatic homopolycyclic compound Arylsulfonic acid or derivatives Azo compound Benzenesulfonate Benzenesulfonyl group Hydrocarbon derivative Monocyclic benzene moiety Organic aluminium salt Organic cation Organic nitrogen compound Organic oxide Organic oxygen compound Organic salt Organic sulfonic acid or derivatives Organonitrogen compound Organooxygen compound Organopnictogen compound Organosulfonic acid Organosulfonic acid or derivatives Organosulfur compound Sulfonyl logp -0.72 ChemAxon pka_strongest_acidic -3.4 ChemAxon pka_strongest_basic -0.59 ChemAxon iupac aluminium(3+) ion 6-hydroxy-5-[(E)-2-(4-sulfophenyl)diazen-1-yl]naphthalene-2-sulfonic acid ChemAxon average_mass 435.387 ChemAxon mono_mass 434.990130569 ChemAxon smiles [Al+3].OC1=CC=C2C=C(C=CC2=C1\N=N\C1=CC=C(C=C1)S(O)(=O)=O)S(O)(=O)=O ChemAxon formula C16H12AlN2O7S2 ChemAxon inchi InChI=1S/C16H12N2O7S2.Al/c19-15-8-1-10-9-13(27(23,24)25)6-7-14(10)16(15)18-17-11-2-4-12(5-3-11)26(20,21)22;/h1-9,19H,(H,20,21,22)(H,23,24,25);/q;+3/b18-17+; ChemAxon inchikey FFVVMXXUKCHQFS-ZAGWXBKKSA-N ChemAxon polar_surface_area 153.69 ChemAxon refractivity 100.05 ChemAxon polarizability 38.61 ChemAxon rotatable_bond_count 4 ChemAxon acceptor_count 9 ChemAxon donor_count 3 ChemAxon physiological_charge -2 ChemAxon formal_charge 3 ChemAxon Specdb::MsMs 95715 Specdb::MsMs 95716 Specdb::MsMs 95717 Specdb::MsMs 160035 Specdb::MsMs 160036 Specdb::MsMs 160037 HMDB37699
