In the structure of the title compound, C15H14ClN5O2, the terminal phenyl ring and the adjacent furan ring subtend a dihedral angle of 6.77 (17)°. The 4-chloro-5-(di-methyl-amino)-pyridazin-3(2H)-one group is linked to the oxa-diazole ring by a methyl-ene bridge, and the dihedral angle between the pyridazine and oxa-diazole rings is 88.66 (14)°. In the crystal, C-H⋯O and C-H⋯N hydrogen bonds extend the structure into a three-dimensional network.
