Abstract: In the title compound, C14H18N2O3S, the 1H-pyrazole ring is approximately planar, with a maximum deviation of 0.005 (1) Å. The dihedral angle formed between the 1H-pyrazole and phenyl rings is 79.09 (5)°. Pairs of intermolecular N-HO and OHN hydrogen bonds form dimers between neighboring molecules, generating R22(10) ring motifs. These dimers are further linked by intermolecular N-HO and O-HN hydrogen bonds into two-dimensional arrays parallel to the ac plane. The crystal structure is also stabilized by C-H interactions.
