Phenazone (INN), phenazon, antipyrine (USAN), or analgesine is an analgesic and antipyretic. It was first synthesized by Ludwig Knorr in 1883.^[1] 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.
