Abstract: The title compound, C₁₂H₁₆N₄O₄S, is composed of two substituted pyrazole rings, which are connected through a sulfone group. The dihedral angle between the two pyrazole rings is 79.1  (1)°. The ethoxycarbonyl substituent is planar and is slightly twisted away from the attached pyrazole ring.
