3, 6-Dinitrophthalic acid underwent degradation with aqueous sodium hydroxide at a room temperature in about 60 days to 3-hydroxy-6-nitrophthalic acid, which gave a yellow color in alkaline medium. The degradation also occurred gradually in aqueous sodium carbonate, but the acid was very stable when it was stored in tablets mixed with anhydrous alkali carbonate.
