Abstract: In the title hydrate, C13H10N4O2S·H2O, the dihedral angles between the central pyrazole ring and its pendant phenyl and thiadiazole rings are 9.93 (8) and 4.56 (7)°, respectively. In the crystal, the components are linked by N-HO, O-HN and O-HO hydrogen bonds, generating  chains incorporating R44(10) loops. A weak C-HO interaction helps to consolidate the packing.
