The compound was described in 1988 by G. Maier and others, who obtained it by pyrolysis of 1,3,5-cyclohexanetrione (phloroglucin, the tautomeric form of phloroglucinol). It has also been obtained by flash vapor pyrolysis of 2,4,6-tris(diazo)cyclohexane-1,3,5-trione (C6N6O3).:p.97 It is stable at room temperature in solution. The pure compound is stable up to −96 °C, at which point it polymerizes.
