%X In the title compound, C16H14ClN3O2S, the dihedral angle between the benzene and pyrazole rings is 52.75 (2)＜, while that between the pyrazole and 4-chlorophenyl rings is 54.0 (3)＜. The terminal sulfonamide group adopts an approximately tetrahedral geometry about the S atom with a C！S！N angle of 108.33 (10)＜. In the crystal, pairs of N！H...N hydrogen bonds lead to the formation of inversion dimers. These dimers are linked via a second pair of N！H...N hydrogen bonds and C！H...O interactions, forming a two-dimensional network lying parallel to the bc plane. The two-dimensional networks are linked via C！H...Cl interactions, forming a three-dimensional structure.
