In the title salt, the cation is protonated at the thiazole N atom and in the anion, the sulfonate group is deprotonated and an intramolecular O—H⋯O hydrogen bond occurs. In the crystal, cation-to-anion N—H⋯O and anion-to-anion O—H⋯O hydrogen bonds link the component ions into (101) sheets.
In the title salt, C7H6N3O2S+·C7H5O6S−, the cation is protonated at the thiazole N atom and the dihedral angle between the nitro group and its attached benzene ring is 3.6 (4)°. In the anion, the sulfonate group is deprotonated and the dihedral angle between the carboxylic acid grouping and its attached ring is 7.1 (4)° and an intramolecular O—H⋯O hydrogen bond occurs. In the crystal, cation-to-anion N—H⋯O and anion-to-anion O—H⋯O hydrogen bonds link the component ions into (101) sheets. Aromatic π–π stacking and weak C—H⋯O and C—H⋯S interactions also occur.
