This compound belongs to the class of organic compounds known as pyrazolo[1',5':1,6]pyrimido[4,5-d]pyridazin-4-ones. These are aromatic heterocyclic compounds containing a pyrimidine fused to both a pyrazole and a pyridazine rings. The resulting ring system carries an oxo group at the 4-position. Here, the pyrimidine ring shares one atom with the pyrazole ring, and no nitrogen atom with the pyrazole ring.
