Popis:	The unknown 5-hydroxy-6(5H)-1,2,4-triazolo[4,3-b]pyridazinones were prepared by rearrangement of 6-hydroxyalkoxy-1,2,4-triazolo[4,3-b]pyridazines in polyphosphoric acid. The reaction was accompanied by the formation of bis(triazolopyrydazine)derivatives. The products were transformed to chloro derivatives
