Abstract
In the title molecule, C14H15N3O4S, the pyrazole ring is aligned at a dihedral angle of 55.5 (1)degrees with respect to the benzene ring; the mean planes of the acetyl substituents are twisted by 13.4 (3) and 30.1 (3)degrees with respect to the pyrazole ring. Intermolecular classical N-H center dot center dot center dot O and weak C-H center dot center dot center dot O hydrogen bonding links the molecules, forming a three-dimensional network architecture in the crystal structure.
