Abstract: In the title compound, C₁₇H₁₄BrClN₄O₂, the pyrazole ring is almost coplanar with the benzene ring [dihedral angle = 0.5 (2)°], whereas the pyrazole ring is close to perpendicular to the 3-chloropyridine ring [dihedral angle = 73.7 (2)°]. An intramolecular C-HO hydrogen bond occurs. The dominant interaction in the crystal packing is an N-HN hydrogen bond, which generates a chain along the c axis. Weak intermolecular C-HO and C-HN contacts are also observed
