Phenazone, or phenazon, is an analgesic. It is formed by reducing diortho-dinitrodiphenyl with sodium amalgam and methyl alcohol, or by heating diphenylene-ortho-dihydrazine with hydrochloric acid to 150 C. It crystallizes in needles which melt at 156 C. Potassium permanganate oxidizes it to pyridazine tetracarboxylic acid.
